Im looking for a STAMPED half dollar expanded shell...I believe our friend Nathan Kranzo sold one....Its not on his website...It's no where to be found...Maybe I'm crazy (well...there's no maybe in that LOL) but I'm thinking with a stamped shell you can flash the back without much heat...

You can flash them, and you can find them for sale on the big auction site.

Not recommended for close-up.

Which Auction site is that??

EBay
At one point the Cafe would filter that out so that's how's it's generally been referred to here.

I believe Royal Magic (Fun, Inc.) manufactures them, but they don't generally sell to individuals, only wholesalers. You should be able to find them at most magic shops for about $20.

But if the only reason for the stamped version is for flashing purposes, my first reaction is that you may be trying to over-prove something -- and something that's not totally necessary. As Dai Vernon used to say, "Don't run if you're not being chased."

If you absolutely feel the need to have everything examined either before or after your routine, there are plenty of ways to add or ditch the gaff so there's nothing for the specs to find. SETH

When John Sturk worked for them, he would sometimes track down a manufacturer of an item by giving me a call. I assume he had the requested item sent to the customer's favorite dealer.

Just get a sicker of a half dollar and put it inside your shell…it works just as well.

It sounds like a coin gaff called Mint Condition
