Start a database right away. I wish I did.
Pick one area you want to collect. You will soon learn you can't have them all.
If you can buy a stack of all new chips. Down the line you will be glad you have them. You can always cash them back in.
If you are married make two matching binders. So if you should get divorced and your wife wants half your collection just hand her her binder.
If you decide to collect roulettes I have over 400 different Vegas traders. The goal is to get complete tables or entire casinos.
See email I'm sending.
