Hello and welcome.

Technically, your items aren't "coins" (pieces of money issued by the government). What you've got are either tokens or medals.
As for value, the short answer is, "it depends". Tokens and medals aren't as popular with collectors as "real coins", so even if something really is "rare", it doesn't make it valuable. I don't know if there are catalogues that list values for items such as yours. You could try an
ebay search to see if similar items have been sold there and what they sold for, but values for exonumia are generally much less consistent than values for coins.
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
