As a general rule, political medals - and these are "medals", not "coins" - are a very niche market: a few people avidly collect them, a few people actively dislike them, and most coin collectors don't really care one way or the other but don't really want them or want to pay much for them.
For Donald Trump items, just like the man himself, it's polarizing - the crowd of "apathetic about it" people will be smaller, and the "love it" and "hate it" crowds will be bigger. As for how all this translates into actual market value for such items... your guess is as good as mine. In the end, "it's worth what someone is prepared to pay". There aren't enough of them around and being bought and sold for any kind of "accepted market value" to be determinable for any one specific medal issue.
For that reason, it's these sorts of things that really do best in an
ebay auction format, rather than a buy-it-now fixed price. Slap it down on
ebay for 99 cents opening bid, and see what happens.
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
