A problem that only gets worse as your collection grows. I definitely agree, from the beginning start a data base, I wish I had. Complete sets or unique chips go on the den wall in frames. Every thing else in 2½ x 2½ holders, in 12 pocket sheets, (all from CT Coins) in 3-ring binders. Stay away from some PVC and vinyl sheets that will leach color from your chips if in direct contact (especially reds). Holders eliminate that problem.
