I have noticed that there has been an increase in the number of coin listings that are possibly fraudulent. I see several listings with coins with amazingly low prices and they are all from relatively new sellers.
At least on of the sellers had an account on a different auction site and his MO was to sell quite a few small items, then sell ONE large ticket coin (>$500) then list a whole pile of high cost coins and then make insurance claims for "lost" coins. He then got quite a few bad reviews and moved on, it appears he has moved here. I tried to get the seller to take photos of the coins, but he wouldn't or couldn't provide any photos except for those he downloaded from a major coin internet coin site.
I called the local Sheriff and was told to not send this man any money.
Anyway, be careful and remember if the price is low, make sure it isn't TOO low. $300-800 for a St. Gaudens $20 Double Eagle sounds GREAT until you find out you just sent a check to a scammer.
