Hello and welcome.

Unfortunately your suspicions are correct. They are both replicas. The Tripoli coin is mass-produced and sold in sets of replica "crusader coins", like the ones sold
here. The Reyes Catolicos is a very commonly replicated coin, what with the connections to Columbus, pirates and all that; yours is not quite as bad as the gilt-bronze ones that often turn up on the forums, but it still bears some similarity to those - such as "R-E-backwardsZ" instead of "REX".
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
