Fred,I do not know how many cards I have.Never count them,but I know it is not near what everyone else seems to have.I know I can't fill a shed and if I could my wife would put me out there with them.I don't separate blanks from used as to me it is the card that fills the spot I need.If I get a better condition card than what I have I replace it.I also follow along with Pat Lamb in that I group my cards by the breakdowns in the Price Guide[Riverboats,Indians,etc.]I go by states within those groups.I can better look up casinos that way.I started in alpha but I had to keep rearranging.
Everyone enjoys collecting in their own way .One way not better or worse than another.It is what you enjoy and what you feel most comfortable with. Also I guess how much time you can devote.Just have fun.
