I remember the D&B in Philly used to have BlackJack tables. I wasn't collecting at the time so I don't remember much about the chips.

You would buy a set amount of chips (like T100 for $10.00) and play with them. They had two odd rules that you could not give chips to another player and you had to run out of all your chips.

By the end you would just push your chips into the betting circle and lose them intentionally (hit me! - but you have 20 against a 6 sir...).

I don't remember the chips being custom, probably like generic fun nite or the like.

Philadelphia has replaced that BJ area with more pool tables.
