I enjoyed Ron Bayne's post & thread about favorite chip molds. To continue that theme, here are 3 of my favorite HOUSE molds in which the casino orders a custom die with their name/logo, etc.

First is the original MGM GRAND house mold, seen on this $20 Baccarat prototype. Alongside is one of the die that created the house mold on such chips (with MGM Grand spelled backwards, of course).

Also shown are the Las Vegas Hilton house mold and the Golden Gate house mold, both from past periods of ownership. Something about them that's striking to me.

(The LV Hilton and Golden Gate pics are from MOGH/ChipGuide.)
