Last week Pete Smith passed along photos of two warped coin slabs he found at the ANA show table of Dave Wnuck. Here are reader thoughts. -Editor

"I don't have too much to add to his description. Both coins came out of an estate in Connecticut. The person who inherited the collection had no idea how they got this way. There were a number of other slabs in the collection, but none were like this."

"I think if you put metal in a microwave it would arc. Perhaps they were in someone's pocket when they threw their clothes in the dryer."

"My initial thought is that they were in a "fireproof" safe that became EXTREMELY hot!"

"The deformed slabs in last week's E-Sylum remind me of deformed slabs that a local coin dealer had. The post office irradiated envelopes and packages after the Post Office in Robbinsville, NJ had anthrax to deal with. The irradiation process heated the coins which heated the slabs. The coin dealer kept the warped slabs as a piece of history."

All interesting theories - thanks, everyone. -Editor

"I didn't think of any of those possibilities. It's nice to have a multi-thousand person numismatic brain trust at our disposal!"
