Hello,
Are there any resources to learn about features of Plaques and jetons, with a focus on European? I think I can guess BG plaques with a low degree of reliability. I've also seen a few from: Abbiati, MSK, and Matsui. I'd like to learn some history of the companies and about their security features. For example, what distinguishes between "nice" ones - clear windows, the "scale" look, etc. Also, can I assume most older plaques with the raised outside bevels are BG...or did the other companies do that as well? Right now I'm just going off of how they look to me or by casino name.

Thanks!

Nate
