The "Shhh, don't tell Mama" is an unauthorized strike. Aqua Gaming, which placed the machine, had a dispute with IGT and was no longer able to obtain strikes. They were in possession of artwork prepared by Global Minting (G) so they took it to Roger Williams Mint (RWM) and had them make the strike. Roger Williams cleverly left the G mintmark in when they made the strike. One was sold on Ebay (To Ray Moritz) and I bought four more from the same seller. I notified IGT and Global and sold them each a strike and did a declaration for their legal departments. IGT and Global sent "Cease and Desist" letters to Aqua and Roger Williams. I don't believe any more strikes of this type are being made although I think the casino still ahs some.
