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 grading also considers other factors than just centering, such as color, impression, eye appeal, the back, perfs, etc. But it will give you a better idea of the range of retail values in the US Classics arena. Over the next several months, I will be offering many hundreds of singles, covering all areas of US stamps, but primarily classics, including extensive coverage of regular issues with much BOB as well.
If it goes well enough, perhaps I will even turn it into a small business. Rest assured, if I do, I will endeavor to make it collector oriented, and maintain the highest ethical standards.
