Buy-in chips, also known as lammers, were awarded at WSOP satellites. They had no cash value, and could only be used to buy into WSOP events or WSOP satellites. However, for years people were allowed to sell them to other players, as long as they didn't cause a nuisance while doing it.
In 2021, near the end of the WSOP, they clamped down on the selling of lammers, which I thought was very unfair to players who had always been used to it. In 2022, the unofficial policy was that lammers were allowed again, but some cashiers were still refusing to take them. It depended upon who you got. I never worried about this because I rarely played satellites, and when I did, it was to actually enter WSOP events in the future.
Now the whole thing is done. Instead, winners will get "tournament buy in credits" in their Caesars Reward accounts, which presumably are non-transferrable.
Anyone playing satellites should know this. If you don't have a use for the tournament buy in credits, don't play.
