The eBay auction for 22 Michael Vick football cards, chewed up and slobbered on by two Missouri dogs, ended Wednesday as the winning bidder dished out $7,400 — with the money expected to be donated to the Humane Society.

The success of that auction, with 31 different bidders, created a craze of 25 other postings this week offering torn up cards featuring the disgraced NFL superstar.

But so far, the original post from Rochelle Steffen, of Cape Girardeau, Mo., has been the only auction to attract droves of bidders.

Steffen gave Monte, her 6-year-old Weimaraner, and Roxie, her Great Dane puppy, every Vick card she owned to destroy. The result: The cards worth $1-to-$10 were crumpled, crimped, chewed, torn and generally in a sorry state. Some even had corners missing.

"When I started this, I only expected to get $100 for a local shelter," Steffen told The Associated Press on Wednesday. "But it's received so much attention. It's for such a good cause."

The gnawed cards were the most expensive Vick items on eBay, with well-preserved rookie cards, autographed jerseys and other collectibles selling for far less.

Vick pleaded guilty to a federal dogfighting charge this week. He will be sentenced Dec. 10.
