That is a great feeling. I got mine just over a year ago so I know how it feels. I had to have the house paid for and be near retirement before I felt I could afford to do it. No matter what my interest in coins will be from here on, I know it will the most expensive coin I ever buy.
JimmyD, I have tracked reputable
TPG silver dollar sales on
ebay for the last three years. For
ebay auction, the 1948 in MS60 has averaged $1688 with shipping. I don't know about buy-it-now prices. Seeing the coin in hand is worth something so if it looks good, paying close to $1800 may not be too bad. You could always offer $1700 and see what happens. As far as my tracking went, there were only eight graded 1948 MS60s auctioned in the last three years with
ebay. This coin is not exactly rare, it is just that it does not come up for sale too often.
