I am relatively new to currency, have some experience on coins Most of the printed media I have seen addresses VF and better notes, particularly 20th century Is there a reference (similar to Numismedia) where there is a full spectrum of prices for a particular note (Fr-Unc)? I have not been able to locate one on multiple searches.
I haven't found one. Usually, I check ebay and if the notes I'm interested in are available in the bulk world listings, I know they'll be worth $1 or less. Anything rare or more desirable will be listed and you can check completed auctions to see what they sold for or if they sold at those prices.
I agree with ikandiggit. There isn't a better place to trend prices for any item. We all wish our coins were valued at what books say, or websites say, but completed listings on ebay is a perfect place to see what the market will pay.
It all depends on the note and year. One of my books has older notes in Fine, but stops around 1988. Most of the notes past that year are FV in that condition. As to whether an online resource has this information, I do not believe so. I would spend the money on a reference book if you wanted a more in-depth approach to the hobby.
I have ben loking at large notes $1 and $2 siver certs, etc. I am trying to find the geometric progression between Goog-VG-F-VF. If I can anchor a F value, that works great, geting a VG for 3/4 of the F and a G6 for about half (Sheldon Scale using geometric progresion) Would this approach ve suitable for extrapolating below F/VF fot items in the $100-$500 at the F level? Thoughts and discussion. I know there is no straightforward simple answer, but hopefully some guides can be socialized
