If people are still being fooled by pressure-cast copies, just wait until those die-struck fakes hit eBay en masse.
As a service to collectors, forums could use workshops on detecting cast fakes in the least.
The die-struck fakes will be a tougher call.
I agree entirely, but in the U.S we have, IMO, a couple of dirty little family secrets they don't want coming out. "They" being the big money folks in our "industry."
First, you can't stop the supply of *anything* as long as the demand and profit is there. The U.S "war on drugs" for the last 30 years has proven that. You reduce supply by first reducing the demand and thus the profit. Supply will stop on it's own once there's no money to be made. Not a lot of altruism in black markets.
But now how many ways are there to stop the demand for fake coins and now fake coins in fake slabs? Demand for fakes would fall off to nil if collectors learned to spot them and stop buying them. But their efforts to learn authentication, assuming that they actually want to, which I doubt, only highlights the fact that the problem is there in the first place. We don't want to scare off new collectors, speculators and investors now do we? Why, wallstreet will be here any day now dumping billions into investment grade slabs, we don't want to scare them away. That's dirty little family secret #1.
What if collectors really did learn to spot fakes and stop buying them? Then they could apply that same knowledge and experience to all their buying and would no longer be a milk cow for TPGs. We wouldn't want that now would we?---Dirty little family secret #2.
