I don't have the Riverside Pick Hobson's token but Dan Wickett has several for sale. In fact he has four different in several grades. If you'd like to see what he has, here's the link:

Scroll down to the Riverside tokens, about 3/4 of the way down this page. To see any token, click on the name of the casino in column one.

Since most casinos have discontinued use of slot token, buying one from a dealer like Dan may be your best bet. They are not very expensive. Good luck!
