I understand the sentiment, but if you put together a used casino set piecemeal, your wallet is likely to pull itself out of your pocket and slit your throat. Take $5 chips, for example. Any oven used $5 chip as a single might run you $3-$30 depending on condition, property, age, etc. That same chip in quantities of 100+, however, might sell here for $70-$350 (or maybe a little more). I can appreciate the romanticism of puttin together a used set piecemeal, but it’s simply not cost effective to the extreme.
Spend a lot of time looking at your chips and sets that others have posted pics of here. A LOT of time. Think about what appeals to you and why, and start narrowing the field. Also take some time to think of what sets might actually be buildable. You might like the look of the Players Club chips from Montana or the Oceanside Card Club or the Normandy Club, but the odds of putting a playable set of those together is slim to none, particularly piecemeal. But you have a VERY good chance of putting together racks of old Foxwoods $1’s and $5’s, Riviera or Virgin River fractionals, and/or Europa $25 chips from bargain bins at the annual chip convention if that’s what you want to do.
Alternatively, buy a set from the classifieds here. Truly, it isn’t cheating. And there’s nothing to say you can’t buy a casino set from the classifieds now and use that while you slowly build a casino set of your own.
If you do decide to piece together something new, be sure to put up a Wanted post in the classifieds here and we’ll help you find the chips. Also be sure to ask a few of us to help you look for them at the convention, even if you will be there yourself. It doesn’t hurt to have multiple sets of eyes looking for them (as long as all those eyes aren’t bidding/shopping against one another).
