The stamp had 499d written on the back of it. It was clearly a listing error.
That's a pretty lame excuse.
I also have like you
inherited a collection from my grandfather.
Most of it in albums and there are notations if a variety
is involved and in the majority of cases he was right on.
It is not a valuable collection money wise, it is to me though since it was my grandfather's.
But if I had found a very valuable stamp there going by what
he believed and marked , do you think I wouldn't have verified it
myself?
Of course I would have.
Ok I'm a stamp collector. You are not. So you say.
But even so you should have found out what you had
before you listed it.
I keep on thinking what you would have happened if this
occurred at a garage sale.

You sell an item for 2 bucks. Then your neighbours tells you
that's worth at least $100.
Are you going to run after the guy yelling
" Heh I want it back, sorry that was the wrong price on it"
or " My wife told you the wrong price"
Anyway good luck to you.
