Scott #13 10ct Type I Used Barely Cancelled RARE. Tiny corner faults at upper right and lower left. Has the characteristic complete lower right shell and since all Type I (both perf and imperf) come from the bottom row of the sheet, has a guide dot in the lower left margin (see detail scan). My store has numerous very nice US classic stamps, including some of the rarest, and I add new ones all the time. George K’s Stamps. The site has large beautiful pictures of every US and UK classic stamp along with tutorials, a number of which I developed, to distinguish the many varieties of US classics as well as a wealth of other information about each stamp. For a more accurate assessment of current value based on the total range of grades, see the PSE (Professional Stamp Experts) pricing guide, which is updated quarterly. Their cert grading also considers other factors than just centering, such as shade, impression, eye appeal, the back, perfs, faults, etc. But it will give you a better idea of the range of retail values in the US Classics arena.
