Hi, After two years (or more...) I know nothing about the following coins in my collection. Heeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeelp, hilfe, na pomosch, ajudo!
IMO number 1 ancient greek. number 2 arabic or islamic coin weight. number 3 venice 15th century number 4 pilgrims token. I am just guessing.
Not enough detail for me to ID from the pictures, but I'll guess... 1 India, 1000-12000AD range. 2 Probably India, I'd start looking around Mughal era. 3 Token, I suspect it's relatively modern 16-1700s maybe much newer. 4 I'd spend my time searching Italian States, anywhere from 1000-16000AD.
