Check out this forged "500 Homerun Club" baseball listed by Ebay seller See*and*ye*shall*find 

Typical and mass-produced set of "500 Homerun Club" forgeries that we've observed in the hundreds upon hundreds.

Ebay seller See*and*ye*shall*find writes "Ball comes with a letter of authenticity from AllStar Enterprises (who?), a well-known sports memorabilia authentication company."

Seriously!!!

Look at this train wreck!!!
