tlmcca : thanks for your help
I had a discussion with this
ebay seller SCANDIMAN
It is obvious his stamp have been reperf, meaning seriously altered, dammaged, almost ruined the stamp at a point to be sold as a space filler... less than $1000.00 on my point of vue

He told me that a potential buyer offered him $1,000.00 if he add it on
ebay which he did. It's been there for over a month and the potential buyer never showed up!
This conversation occured last week. Should I be surprised to see that this vendor kept his item to be sold at this ridiculous price? No I'm not... he is waiting for a fish...
He asked me to make an offer...I refused because I did not want to insult him with a ridiculous offer ($100.00). He said he would not sell it under $500.
Does it worth $500.00? Any comment from the Community?
