Knowledge and most everything you had done and continue to do for this hobby. For that we are all grateful. I guess we will have to agree (to disagree) on this one. I am NOT trying to argue...I am debating 😀
I don't have any 100% concrete evidence... but I think I that having 3 different chip molds/colors in a 4 year span doesn't seem right. They have a $1 black H/C and a $20 black Zigzag?
I'm sure that it is possible...and other casinos that changed hands rapidly did change chips, colors, manufactures....
Did your Las Vegas dealer get the chips from a guy named Will Posthumus? (Spelling) I am told that Will got the chips and some match covers from Frank Vaccaro himself. He sold some as Modesto and others desired to sell them as from Henderson. I don't know if he sold a big lot to any individual.
Frank Vaccaro passed away in 2007..... so Will would of gotten then before that time. How long or what year...I don't know. I will reach out to family members of Frank and get more info...if it is out there.
