1968 2c Roll On Ebay

That is crazy. The latest C&B magazine has retailers selling them for $2,500.

Looking at the bidding it seems to have been a bidding war. The winner would have been devastated seeing the winning bid jump from $2,100 to almost $4,500 in the last minute.
There are two lessons here
- If the buyer had "sniped" in the last few seconds he would have saved himself over $2,000
- If the buyer had realised he can buy one for $2,500 retail he would also have saved himself $2,000.
