On delcampe Cuba stamp were sold under $1. Following is the screen shot.
This stamp is not rare and currently available on delcampe under 50 cents.!! Please look following screenshot about current auction. So not sure why buyer is not buying this and wants to buy for $16.!!
Even FDC was sold under $3.
So why someone is paying more than $16.!! for just a single MNH stamp. What do you think about this transaction?
