Before I continue, below are links showing hundreds of examples of forged Mickey Mantle baseballs, photos, etc. found on Ebay (the most dangerous place to buy autographs if you're a casual collector or impulse buyer).

Check out these two Mickey Mantle forged baseball bats (with fake inscriptions) listed by Ebay seller Southfloridafishermen.

These are horrid and laughable.

Note there are no bids on this crap.  At the prices listed, if the autographs were authentic, they would be a steal.

The first one is a forged Mickey Mantle bat with the inscriptions "536 Hrs, NO 7 and HOF 74.

Laughable.

Here is the second forged Mickey Mantle bat with the same fake inscriptions.

Again, laughable.
