Is the PCGS rarity scale is relevant these days
I am interested in whether the PCGS rarity scale is relevant for modern coin collectors. Survival estimation is difficult when they are not being released into circulation. For example, there were many Kennedy Half dollars that were not proof,ie., were production strikes, that dont merit grading due to the high cost of grading. However PCGS bulk grading requirements can incentivize dealers to make bulk submissions. Huge quantities of high quality new graded coins can come on the market for a date that is thinly populated PCGS wise, but heavily minted, that are therefore by no means rare. Can someone esplain this market to me. The market for the highest of the high grades is a huge jump, from say, 64 to 65 for production strikes or 69 to 70 for proof strikes. Remember that the longer a series goes on the more difficult it is to achieve a highly graded PCGS graded set.
