I wouldn't sell someone a common circulated silver coin like that for several times fair market value. It seems to me the buyer wasn't very knowledgeable in this case. I'm not going to condemn the seller here since he didn't force anyone to pay that price. Me, I wouldn't want to live with the guilt of taking advantage of someone.
I agree, but how many times have we seen/heard about "cherrypickers" finding such great deals? What about error hunters? Isn't that the same, only reversed? How often do we see threads that state, I found a $50 coin that was actually worth $500, (fmv) so I alerted the seller, and paid them the $500. Just an extreme example, but I think you get the point.
I melt anything to make a buck to keep the lights on and food in the fridge. I have broken apart thousands of silver proof sets, sent beautiful, engraved 150 year old pocket watches to the refinery and will keep doing so as long as the refinery pays more than the collector will. Medals, jewelry, coins; you name it. No big deal. It just makes the survivors rarer.
your coin had PVC (green) damage on it. you should have educated your buyer as to what the coin was worth. maybe $6-10. $19 was ripping them off. if they go to sell it and only get $6-10 it might poison them against buying more coins and just not collect coins anymore.
To be fair, you did ask "what is this worth", not "what can a greedy and unethical seller get for it from an uninformed buyer".
Alright, I'm supposed to be neutral here, but I'm going to throw you one question, and am looking for a serious answer. Why, if you asked for $19 and got it from that buyer, and feel that makes the coin worth the $19, do you then come on CT and ask others what the coin is worth? .
