The sacred cross with the corresponding letters in 4 sections of reverse are very usual on Byzantine coins. However, detecting the figure on obverse is sometime very difficult due to low condition and design of such coins. The standing person on the obverse of the following coin is holding a cross with his or her right hand. But how can I determine his identity or the name of the Emperor under whom the coin was struck. Please post your opinion if you can. The coin weighs 5.45 g. Thanks..

So the coin pertains to the Class C of anonymous folles, with Christ on obverse raising hand and holding Gospels. It was struck under Michael IV who reigned from 1034 to 1041 AD. There's also a famous icon figuring out this obverse.
One point to remember when studying the Anonymous series is that we can call the coin Class C and hope/expect it to remain that way while it is not out of reason to have someone do an extensive study of the series and make some adjustments on the dating based on new hoard and overstrike evidence. Nothing in numismatics is immune from new generations of scientists tweaking old studies but we still have it better than the people who study plants and animals and what they have done to 'Scientific' names as assigned by Linnaeus and other early taxonomists. Will your coin be attributed to Michael IV in another century? Maybe, but it should still be a Class C unless someone decides we need to separate C into C1 and C2 like they did with the A group. Are coins marked with a ruler name immune from this sort of tweaking? Ask students of Parthians marked Arsakos and English pennies marked Henry.
