The aim of this study is to investigate the relationship between spot and futures price of GOLD COINS in Iran and how market information spread between these markets, and analysis between changes in cash and futures price volatility is the daily GOLD COINS. Daily data for the future price of GOLD COINS collected in 2012 from Iran Mercantile Exchange, has been used. To examine the relationship between spot price and futures price of GOLD COINS multiple regression models, vector Autoregressive, GARCH and Granger causality test is used. The results showed that changes in futures and spot coin price does not have a significant relation in the VAR model and multiple regression, But the spot and futures price volatility have an effective relationship. Granger causality tests also showed there is a relation from the spot price to the futures price changes. But the spot price and futures price volatility results indicate that this is Duplex relationship between markets, there is information flow between the two markets as a perfect.

We can search the subject of religious tax for bills in three chapters following of jurisprudence: 1-religious tax of the property business 2- religious tax of GOLD COINS and silver COINS 3-judicial leader. In this article, it will be proved based on the second title namely religious tax of GOLD COINS and silver COINS and by this reason we discuss the six methods. Among the six methods, fifth and sixth are correct because of at the fifth reason I mean at the narrative of Mohammad Ibn Moslem we see the word and at the sixth reason we see some narrative such as narrative of Hassan Ibn Ali Ibn Vasha that proves the necessity of payment for it at every kind of money.

Investors usually are challenged in an environment marked by uncertainty caused by the financial markets operation. Therefore, it is essential that information to investors in the field of financial risk and return and correlation is to take advantage of the opportunities available. The aim of this study was to investigate the correlation between the returns on financial assets pairs (GOLD COINS, dollar, and stock) using the new approach of Hilbert-Huang transform in the period from 25/03 / 2001-21/12/2015. The results of this study show that correlation is not constant over time. During the 25/03/2001-22/9/2013 period between two sets of COINS and dollar, coin is the leading factor; between COINS and stock, again the coin is the leading factor; however, between the dollar and stocks, the dollar has been the leading factor. And in the period 23/09/2013-21/12/2015 between two sets of COINS and dollar, dollar was a leader; between the COINS and stocks, the leading factor was the stock; and between the dollar and stocks, the dollar has been the leading factor.

Objective: Margin in derivatives markets, such as futures markets, is used as a means of controlling the risk of future prospective obligations. On the other hand, margin is regarded as trading expenses and as one of the factors influencing futures market. Methods: Accordingly, in this paper, the effect of margin changes on futures contracts has been studied regarding Iran mercantile exchange in terms of return, risk and liquidity from 2016 to 2017. To do so, three approaches were used: estimating separate equations, seemingly unrelated equations and vector auto regression along with impulse response analysis. Results: Based on the results, margin changes had a significant effect on returns and liquidity, but no significant effect on volatility. Also, the effects of margin change shocks on all three variables of return, volatility and liquidity were not stable, and more specifically the rate of damping of this effect on liquidity is less than the effect on the other variables. Conclusion: In other word, margin changes affect futures market return and liquidity, yet this is not a stable effect. These results can be helpful for futures market policy makers and investors.

COINS are the most convincing documents used in the definitive chronology and measurement of political, economic and cultural transformations of past eras. COINS of each period represents the political sovereignty, script, language, art, religion, civilization, socio-economic status, trade relations of the nation and the countries of their past. Numismatics is an interdisciplinary knowledge that provides unique information to archaeologists, historians, sociologists and social scientists, political scientists, economics, linguistics, art and symbolism, etc. This is precisely why reflection in this group of archaeological evidence is important for scholars, historians, and archaeologists. The Bavand dynasty/Bavandian (651-1349 AD) were one of the Shiite families that for centuries, especially during the Abbasid caliphate, ruled and minted COINS in the northern regions of the Alborz Mountains. Although the Bavandian were often independent rulers, but were sometimes subjugated by their contemporary caliphs and sultans. Now, the question arises that with which characteristics of the Bavandian COINS can be used to distinguish from other COINS of the Islamic era? The aim is to find out how the Bavandian differentiated their COINS from the COINS of the Abbasid caliphs and, and precisely, depending on which of the local and regional governments they minted their COINS. The results of the present study show that the Bavandian struck COINS to prove their sovereignty, consolidate their power and their relative independence. Although due to politicalsecurity reasons, they had to temporize with the Abbasid caliphs, but by tapping the phrase "Ali Wali Allah" on the back of the COINS, they have managed to establish themselves as a Shiite government independent of the caliphs.

Ratifying a bill in the Judicial Commission of Islamic Consultative Assembly (Majlis) on setting registration fee of Dowry over 14 GOLD COINS in the time of registering marriage contract (Nikah), each spouse 50% , and depositing it into the Fund of Providing Dowry for Needy Couples, has put the family law on the threshold of drastic transformation. Although this change is made to serve the legal institution of marriage and reduce the amount of dowry as well as facilitate the marriage process, but its functionality is under serious doubt and even it appears that its negative consequences far outweigh any positives. Bills ratified without considering the rights of the parties in the marriage contract not only could provide a platform for men to abuse but also create unfavorable situation for women and causes girls and women as well as men be reluctant towards the marriage compared to the past. This is the fact that women may assume that marriage not only limit their freedoms, but also their life could also be faced with financial and economic threats. Thus, they gain fewer financial benefits in their common life and in order to get rid of a wrong and unsuitable marriage, they must sacrifice their ownership and sustainheavy and unfair costs. Therefore, it is highly recommended for new bills, while holding a compressive approach towards liberty and contractual rights, to provide the goals of the legal system and secure the rights of both parties. Consequently, the current study by descriptive- analytic approach and by collecting data from the library sources, while attempts to survey the fundamental and legal aspects of this bill, also provides solutions and suggestions with the view on the couple's legal system of in France.

COINS are of great importance in presenting different nations’ culture, beliefs and religion and reflect their economic status. By examining each nation’s COINS, precise judgements about their past and present identities are possible. From this viewpoint, the Sassanid COINS have special status because, on their two faces, there are numerous pictorial elements, such as the crescent and stars, the holy fire, altars, priests and religious equipments, various kinds of jewels and ornaments, and the patterns of the period’s clothes. Each of these elements carries extensive religious, cultural and mythological concepts. The way these COINS were made brought about, for the first time, a revolution in the process of easy and fast production of COINS.The Sassanid COINS forms were inspired by the Ashkanian ones. With the rise of Islam, the COINS continued to live as a tool of trade with a little change until the end of the ‘Abbaside period. For centuries, these COINS were used as currency exchange in the middle East, Mesopotamia, Asia Minor, the eastern parts of Europe and the northern parts of Africa. The Sassanids’ economic power and their love for Irans’ glorification caused the COINS to enjoy a unique status.By means of a new method in numismatics, the author has studied the treasure of the COINS in Urmia Museum for two and half years and this article is just a partial presentation of the research findings.

One of the most diverse historical and archeological evidences of the Timurid period are the COINS that have been minted with various motifs and provide valuable information. In addition, they are worthy of attention in terms of framing. Due to the variety of framings,This investigation seeks to investigate and evaluate the various framing forms used to frame COINS in the Timurid period, whose investigation yields valuable data for recognizing a portion of the visual patterns found in the Timurid period's art. The most important question in this search is the different types of Timurid COINS. The intended research is fundamental in terms of purpose and descriptive and analytical in terms of method. The sampling process was purposeful and selective, and after preliminary library studies, 15 Timurid era COINS from the Ashmolean, David, and Malek museums and the personal collection of Komesh Semnan were selected and studied. Based on the results, the frames of the samples can be divided into 3 types: central, bordered, and combined. "central framing", includes samples where one fifth of the surface area of the sample. "bordered framing", includes examples that are close to the edge of the narrow band around the COINS surface. "combined framing", three-fifths of the surface from the center to the outside and one-fifth of the surface from the outer edge to the center have patterns.The largest number of types in historical order include mixed framing with 19 cases, central with 7 samples, and bordered with 4 samples. Among the types, the combined frames have the highest number and variety of designs, which can be seen in the central role of the samples. Historically, this species has been divided into three types, circle, seven feathers; square, four feathers; polygonal, eight feathers; and six feathers. There are six feather types, of which four feathers have 8 cases, the square has 4 samples, the circle has 2 samples, and the rest has 1 sample. The most diverse type of mixed framing belonging to the era of Shahrukh is the circle, square, four-part, multi-armed, eight-part, and six-part patterns.
