For the last 2 years I've collected $10 Las Vegas strikes. I've had pretty good success in getting at least one variation of most. However, with the "chase" strikes and some of the newer issues that are very limited in number it is difficult,if not impossible,to obtain all. I realized in the beginning that I would not be able to have all that are issued but I am thinking about going to something more specialized. What are some of the things you guys specialize in? In other words, what is the "theme" of your collection?
