I've seen some phoney pennies but DDCC is one of the best- phonies.
Actually the patent pump angle is vanilla. A lot of scams pump worthless patents. And then hope the word "royalty" soars into the sky.
The brazen part was their pretending to be a gold broker, and then PRing nonsense 6 months later, and the absence of an 8K providing details. Ought to be interesting if they try again. ;)
