Let;'s ID some medallions and tokens! (3) | replicas

The first piece is imitation Ottoman, looks like a Turkish coin but with garbled legend. Even the ascension date is made up - (AH) 1227 (which even looks like 12027). There've never been coins (or official medallions) with this date. Cheap jewelry piece.

The second piece is a very crude, hand made, coronation medal of George V of the UK. They did use the famous Pistrucci's design of St.George slaying the dragon which is featured on some crowns and sovereigns. There are tons of different coronation medals for each British monarch starting with Victoria, with various degrees of sophistication (your is on the lower end). I don't really see anything about a website, I'd say it was made before the internet.

Piece three is an imitation of a Roman coin, and it might have been a button.
