There was no 1973-S business strike clad issue. The 73-S comes as silver Unc, silver proof, and clad proof. A business strike SHOULD be silver clad. (I say should be because recently a clad one WAS found still in the original government blue envelope. It was struck on a rejected clad proof blank by accident.) If you do have a 73-S unc clad it would probably be a four figure coin.
I agree with you totally but 20% is a bit much. I don't think the wear of a coin could ever add up to 20% however I could be wrong. The most I've been able to verify is .5 to .18 of a gram lost due to circulation.
I just went to a show and was asking/looking for a low grade seated dollar. Had a long talk with dealer who claimed that his guess was about 80% of seated and Trade dollars were fake. I asked about all the fakes on ebay of Bust halves and he showed me the scales he uses to weigh everything he buys. When askd about the weight variance for low grade AG/G he said they would never be more than 10% under. Anyway I bought a Seated Dollar from him. I hope its real!!!??!! Lack
10% under speaking of Seated Dollar or Trade Dollar even w/highest wear. (AG/G) He basically said even that worn they would still be over 90% of the original weight. His claim was that the fakes of these were quite a bit lighter in weight. After what Doug said in a previous post I'm wondering if that is an accurate statement. It sounded like the real coin would not be anywhere near 10% lighter due to wear. Lack
