How to determine if a pin is real/fake?

[Topnotchsy]

Hey,

I've been looking at a pin that I was thinking of picking up and realized I have no idea how to tell if a pin is real or fake (or a recent reproduction).

I looked back at some posts here that mentioned some pretty good looking fakes, but nothing on how to ID them.

I'd rather not post the pin publicly, because I think it probably fits the collection if there's a way to help without that. The pin I am looking at is not super intricate (more a basic pin with some words on it). The font and lettering looks like the other examples I've come across, and the back of the pin definitively looks old, but I know that's not enough. Front looks cleaner than other copies I've seen, which is part of the reason I'm concerned.

Any help or guidance is much appreciated. If resources on this already exist, I'd appreciate a pointer to them. Thanks!
