They're now my favorites too. I originally started with the $10 strikes, since my original interest was in collecting bowling related collectibles from the casinos... strikes, chips, slot cards, etc. I think I have just about every chip and strike (except for 2 very high value ones) that are bowling related. Along the way I just got hooked on $7 strikes and now have about 80 of them. The slot cards just sorta fell into it along the way too. Since I travel alot, it gives me something to do in the evenings when I'm not working and I've been trying to see how many cards I can get with my own name on them :)
It's been fun to say the least.
Oh, and thanks for your great silver strike guide, it's been an invaluable help along the way!
