Help

Can anyone please tell me about strikes that have no casino name and are a series such as I have a bell star silver strike with 3 guns on the right and left brass part. On the flip side, it says "gunfighter series" and in center with "wanted dead or alive: contact county sheriff $10,000, Finger pointing on left and finger pointing on right, "reward".

There is no date or mint mark. Any information would be greatly appreciated.
