How Can You Tell If A Slab Is Fake?

I have 0 respect for these counterfeiters. If it were up to me I'd hang em all.

It's always a debate between me and my friends about how counterfeiting is really affecting the market. I've only seen one fake Trade dollar through my travels. Any high end coin ie $300-$1000 I make sure I buy from a numistist dealer and check the photograde.

I was thinking about buying some fake coins and hiding them in my sock drawer so if I get robbed the thieves will think they got the big stash and not find my real coin stash.

From what I heard they can't tell fake coins from real coins. One would think if they found a roll of double Eagles in my sock drawer they would do a bee line to the closest cash for gold place.

Oh this merry game of cat and mouse. :-)

Some time back a dealer I know showed me a slab. In it was a coin that had nothing to do with what was printed on the tag inside. He told me he opened it, replaced the coin with an obviously wrong one, resealed it. I could not tell how nor where it was ever opened.
Another dealer showed me obvious fake coins in a fake slab. I only knew they were all fake since the coin was a 1913 Liberty Head Nickel.
I've seen many fake slabs at coin shows where they were put on display for people to see just how good they are now being made. In reality the average person just can't tell. In many instances even dealers can't tell.
Fake slabs and fake coins are getting so good, many realllllly look real.
At a flea market a dealer was selling coins such as 1916D Merc's, 1921 Walking Liberty halves and lots more. It was only obvious they had to be fake since they were only $5 each. You really just can't tell anymore.
