Though it's unlikely he will get prosecuted, the mere "offering" to sell a VIN tag is illegal. (it's a statutorily sacrosanct item) I would imagine that ebay will yank that ad in the near future. As for other actions, it is equally illegal to buy a VIN tag or sell one or install it on any car other than the one it was originaly riveted on at the factory.
Yes, Jeff you are safe in keeping yours...right next to your .44 Magnum by the bed. That is until the feds come to pry them out of your cold dead hands (Sorry, I was getting a little Charleton Heston-y there at the end)
