...if he was sure those chips were from Las Vegas. Here's his answer:

"Hi: Have had so many questions on this chip. Some take the same beliefs as me and others say no. The catalogues say they are from the S S in LV.
Chip Rack and Casino Chip Guide both rate them as high, maybe too high.
Chip Rack published 2004, the Casino Guide 2005. The 50c Bud Jones die cards/aces mould was exclusively sold on the tables at LV. The Silver Slipper in LV received a shipment of 30000 $1 red and $5000 black also.
The Red aces/cards $1 WAS used on the tables for awhile and then cancelled with an orange marker in the centre and pulled off the tables.
For why I do not know but these chips were not up to par as to what Howard Hughes was used to using. The chip I have on Ebay has a slight orange mark on one side.($1). It was used on the tables. The last one I sold went to a USA Federal Agent and he will be very happy to receive it. I don't want to convince you to buy one. It is up to you. Either pass or keep watch. I have but one left and that will be the end of them as far as I am concerned. Other people have sold them why am I being attacked. Your email is the 6th I received in 12 hours attacking me for selling this chip. If they don't want to buy it they don't have to. I offer a money back guarantee and have done with the 6 others I have sold. Not one wanted their $$$ refunded. If you want the chip and can afford the price then the decision is up to you. If you are in doubt leave it for someone else and maybe later pick it up. Regards. Jcmmr51998"
