Chipguide query is your friend:
http://www.themogh.org/cg_query.php
But I gave it a shot already -- the tool only sorts Paulson molds by H&C or house, and
IHC (although allowed in individual entries) is not a query parameter.
So, short answer is nope. Best bet is to select each of the Vegas strip casinos you might visit and see if they have a 43mm chip listed. $5 Mandalay Bay (house mold) is the only one I know of for sure, but I'd be shocked if there weren't at least a couple of others.
