The listing, USA CTC - Polio Vaccine Developed, mint has ended.
USA stamp from the "Celebrate the Century" series from 1998 to 2000.
These stamps were ONLY available as sheets of 15 different designs, so if you want a single stamp you would have to buy a full sheet. There were 10 different sheets available, one for each decade (1900's through 1990's).
Single mint stamps such as this are rarely available and are great for people that wish to collect stamps with particular subjects and themes.
Full sheets (15 different stamp designs) of these now have a catalog value of over $12.50 (2012 catalog value). One of the large stamp mail order companies (...name begins with an "M"..) charges $16.75 for a sheet and $1.95 for a single such as the one offered here (plus $2.90 postage). Thus, this single stamp from this particular stamp company would cost you $4.85 !
--> My cost is much more reasonable (only about 1/3 !). The minimum bid takes into account my out of pocket costs including non-tracked first class mail and the current exchange rate for credits. Note: If you wish USPS tracking, then you'll need to pay for $2.54 for USPS 1st Class Parcel tracking (the cheapest available).
--> GIN of 9,000 is available
Condition: full gum, mint never hinged, post office fresh
Note: the way these stamps were perforated on the full sheet of 15, some stamps may have a slight colored line on one edge of the perforations; this is due to the perforating equipment not always being spot-on and picked up some of the printed part of the sheet.
I have up to 3 of the particular CTC stamp that is illustrated, the scan is representative of what you will receive (if I have more than one) or the actual stamp if I only have one.
