I don't understand why people are insisting you made a bad trade. You traded bullion for numismatic coins. On the other end, he wanted to trade numismatic coins for bullion. Just the silver content of the peace dollars is ~$34. The ones pictured are probably worth $23 each. So that is $46. The slabbed coins definitely total over $30. Then you have the war nickel as a bonus. This was a trade. There was an even exchange. No profit to be made on either side. If you like the coins you received more than the ones you traded, you did well.
Here are some pics of the 1924 peace dollar ( I can't take them our of the holder until my capsules arrive , sorry ! )
Perhaps, if the OP were to tell us how the two Peace dollars were represented to him, this would clear a few things up. Did the trading partner claim they both would grade 63, or was this the OP's assumption? Did the OP place the coins into and write on the flips, or is this how he received them? As for trading bullion for numismatic, this appears to be true only in part. If, as the OP explained, he viewed the trade as being one ASE for the moderns, going on Mr. Travis' estimates, this seems quite reasonable. However, a straight trade of one ASE for one Peace (in shown conditions), and even when considering the common "silver dollar premium", was most certainly less than the OP was hoping for. While not terrible, it seems clear that TC's intent when entering into the trade was to come out on top, and had the two Peace been of the aforementioned grade, he would have. Again, much depends on what the OP thought he was getting, even if when averaged out the trade was not that bad. Perhaps the biggest lesson to be learned by the OP is to know what he is getting before trading/selling/whatever instead of after.
