Yo Bubba, Welcome to the strikepoint...check this site out
http://www.silverstrikers.com/ and click on the oneline catalog button on the left of the screen. Here you will find all silver strikes made and pictures for each casino.
The casinos nor IGT (Manufacture) will tell us how many of any of the strikes unless it is stamped in the strike when made. Several casinos had what we call short runs. Meaning they only had the strikes in the machines for a minimum amount of time before the strike was pulled or the machines removed. The best way to find out which ones are which is buy a guide. There are several out there. Everyone has his own opinion which ones is best. Check us out and then join the club!! There are a great bunch of people just waiting to meet you.
