Silver Islamic coins

Good day everyone. Is it possible to determine the type of these coins, the approximate period of minting and the locality.
I understand that the coins are almost completely killed, and their value is zero, but it's a pity to throw them away.


The larger is likely the Ottoman Empire, the second is smaller - most likely akçe - Crimean Khanate.

Here's a list of 66 silver coins of the Crimean Khanate, of about the right weight and diameter. With your second coin in hand you can look through for a match if you wish.

Similarly, here's a list of 44 silver Ottoman coins of about the right weight and diameter you can look through if you wish for a match to your first coin.
