That is eBay, not forum prices. If you list this coin on there you are likely to get more than you will on here.
Graded Casascius coins sell for (sometimes substantially) more on eBay than they do on the forum. It has been that way for a while.
The reason the majority of us choose not to sell these coins on there is because of high fees, and high risk.
At 13.4%, eBay and PayPal fees hurt your margins drastically. Not many of us like PayPal, due to the chance you could become the victim of a chargeback later down the line - the biggest risk of all.
~2 BTC for your coin is about right in current market on the forum (judging recent prices). An ungraded Silver with Gilt sold on here a couple days ago for 2 BTC.
Good luck man
@SaltySpitoon - OgNasty's coin was an MS65, which sold for 2 BTC
