This auction is for an 1865 Seated Liberty $ that is definitely a cast counterfeit ... the current high bidder is willing to offer $122 dollars for it, but if you review his feedback he/she has been willing to pay $1200 for a slabbed EF40 "cleaned", and $350 for a plugged $. Some time down the road this person will try to unload these items and may be surprised. Back to the auction

Seated dollar. Compare the dates.

Electotypes are a different story. They can usually only be detected under 10x magnification and by weight. Here's an electotype from my collection.
