I am in Las Vegas and if anyone does want something in particular... Let me know by sending me a DM. The one thing to keep in mind with buying live chips is that sure the face value of a chip is say $1, but the gas, parking, time,
eBay Fees, Paypal Fees, etc... has to be figured in for all this. Parking is NOT cheap here in certain casinos. The Wynn is free along with the Venetian, but all MGM and most of Caesar's properties have a pretty healthy charge to park if you are there longer than an hour.
This is why people will still sell a single $1 chip for $4.99 to make it even worth their while. Packing, shipping and going to and from the post office costs a little too. I used to think it was high until I started getting chips myself. This could also put the buyer in a spot with the casino because taking home a few $1 and $5 chips they do not care much about, but try walking out with a rack of chips and it could cause you problems. I know a guy that got stopped for it and ID'd for doing it. So I would imagine if he keeps it up he could get 86'd. It is possible, but I do not know how likely. This could be seen as a potential security issue.
I was told by a lady at the Rio cage during the WSOP tournament that taking chips from the casino cage for the purpose of collecting is against the NGC rules (I did not look this up and don't really care to, but this was said to me once when I got a few of the WSOP chips for the 50th year anniverasary). She basically said that the chips you get from the cage have to be used to play. So I said ok and got some chips to play and sat and played. problem solved.
Dont get me wrong, most people at the cage do not care and are cool doing this. Sometimes if they are real cool and if it is possible, they will give you a mint chip in the back, but don't count on it. Some casinos you can buy at the cage and others you can only buy chips at the tables themselves. It is not as uniform of a process as you might think. I have chips from literally every casino on the strip and from downtown as well. I walked into each casino and got a few for me mostly without hassle, but these were just getting the $1 and the $5 chips (1 of each denomination).
So if anyone is looking for something specific and respects my time and effort will pay the proper reasonable premium I will see what I can do for you.
