I want tell Thank you one more time for everyone. Today I was in three coin stores for appreisal my coin. One give me a 1300$ offer, second one 1500$, and third 1550$. I decide that it is too low and make auction on ebay. Starting bid I put 2200, and buy it now-3400$. Right after 3 minutes my coin was sold for full Buy it now price.
Sounds like our estimates may have been a bit low, at least in one buyer's opinion. Make VERY SURE that you ship the coin with full insurance and tracking! You'll probably find that Registered Mail is your least expensive option, and it's the most secure. I'm always a bit nervous about selling such high-value items on eBay, for fear that a buyer will try to scam me with "I got an empty package" or "coin was fake". But you can see who bought your coin and what their feedback is like, and judge for yourself. Congratulations!
And this is certain according to what formula??? Coins can and do go either way over time. Both up or down.
That coin probably had dated price values due to no sales in recent years...I,m sure your buyer got a great deal from you. Congrats.
