Virgin Mary in a grilled cheese sandwich. Starting bid on eBay: $3000
"I made this sandwich 10 years ago, when I took a bite out of it, I saw a face looking up at me, It was Virgin Mary starring back at me, I was in total shock, I would like to point out there is no mold or disingration, The item has not been preserved or anything, It has been keep in a plastic case, not a special one that seals out air or potiental mold or bacteria, it is like a miracle, It has just preserved itself which in itself I consider a miracle, people ask me if I have had blessings since she has been in my home, I do feel I have, I have won $70,000 (total) on different occasions at the casino near by my house, I can show the recipts to the high bidder if they are interested..."
