Looks to be the size of a 2 reales, so I'd say it likely is a period counterfeit. I've seen and owned some brass ones.
Do you think it could be like this one? It indicates it was found by Don in SJ who is a member here but I couldn't find the thread he originally posted about it.
Great find. I like those pillar buttons a lot. Only have 2.
Thought I recognized a couple of those 1744 buttons in the link provided by Mackaydon. Sure enough, theyre mine (GWWJR). LOL
