What grade is the coin? Can you see any details on it?
Are you saying scrubbed, because it is so worn, the details are missing (scrubbed off) or are there scratches all over it? Better off to use the term worn and not scrubbed, if it is just worn.
In the NN issue of 3-6-12, on page 38, it lists the cheapest 1797 in AG-3 as $75, so it can't be that far off the price, unless the grade is lower?
