Hello and welcome. 
The one on the left is from Turkey, when it was part of the Ottoman Empire. Struck in "Islambul", the official name for Istanbul at the time, early in the reign of the sultan Selim III (late AD 1700s). Similar to this coin on zeno.ru, though we will need to see the other side to narrow down the actual date of issue.
The one on the right is also "from Turkey", but much older; it is indeed Byzantine, Constantinople mint. Probably dating sometime between AD 600 and 900, though we will need to see the other side to get anything like an accurate date.

Don't say "infinitely" when you mean "very"; otherwise, you'll have no word left when you want to talk about something really infinite. - C. S. Lewis
