Focus, Focus, Focus, Focus........

I personally don't care if I fill up an album. Concentrate on getting most of the coins in good shape and don't sweat the stuff that you'd have to trade your car in for. Eventually, you'll get to the point where you don't have anything left but the high dollar keys. Once I get to that point I'll start laying out serious cash. Until then I'll just keep skipping the really high dollar slots and get the highest grade crap dates that I can find.
