Cathedral Art(Abbey & CA Gift) You Are My Love Pocket Token, One Size, Silver

What material is this coin made of?

Does PT107 mean that this item has a quantity of 107? or is it just one token per order?

What is the correct size of this item? The title says 1-inch, the picture shows 1.9" or 4cm (which isn't equal either).

How many tokens do I get ?
