I have seen a few threads here about RDC chips being attributed to RD Casino (aka Resorts Dealer Casino). This matches TGT which shows it as being in Margate NJ, and is a gaming school for AC.

Cashcoinconnection also has pictures of RDC chips as being from a North Dakota charity casino.

Are these 2 completely different chips?

Here is my own picture of an RDC chip I have on Ebay. This matches the picture on cashcoinconnection.
I thought I had also seen the same picture being referred to as the one from the dealer school as well by AC collectors.
If these are 2 different chips that exist, does anyone have a pic of both to clarify? Thanks.
