This stamp was sold for only $0.60 (60 cents). All new collectors need to notice this before buying this stamp or any other stamps or FDC other wise you are in big trouble if you don't do your research about pricing as well as who is seller, seller feedback etc.
Looks like this is genuine transaction because Seller has 9600+ feedback, 2 different bidder and 2 bid in this auction which indicates that no Shill bidding happens to increase price.
I hope this kind of material will help to new collector.
Even FDC don't appreciate too much. $1.58 only after 42+ years. Is it not amazing.!!.
