Hi
Been searching for a loooong time for these:
Butter coin or equiv (supposedly can mix flipper and folding coin routines into 1 gimmick)
Stretched coin american. I have the tango quarter but I saw a longer stretched penny a while back...that's what I was after! A nice long stretch
Coin fusion v1 (a penny is fused into a quarter in a layered fashion )
Coin fusion v2 ( 2 coins fused side to side)

If anyone is willing to part with any of the above or knows a maker that would do such work please let me know (I have asked some of the big coin engineers and they are not able to do most these gimmick types)

Web search is your friend.

That one I do have yes! There was another same name but it was more of the Penny melted into the quarter at an angle

Anyone know if there are Butter-coin vendors? Or the very long stretched Penny? Those seem to be harder to find for me. I see a butter coin seller on eBay but it's a seller I was told from a few collectors NOT to buy from.

Check your PM. I have the Butter Coin.
