During a discussion on CG and chips the Brass Elephant came up and I meant to post this awhile ago but forgot.
Where exactly did the attribution of them being from a Vegas Brothel/StripClub come from? Las Vegas hasn't had Brothels since 51' which Im guessing predates these chips.

A few years ago there were some Paulson chips discovered to be from here and in the lot of chips were a bunch of these Suits chips. The ones were heavily used with many having burn marks consistent with chips being used in a card room. This seems like probable provenance to assign them here as opposed to Vegas. Thoughts?
