I'm going to use the Grey Sheet so that I don't let the values get too far out of hand. The 1809 half cent comes in 6 Cohen varieties. Here they are listed with their Rarity values as reported in Manley's book: C-1 R-5+ C-2 R-3 C-3 R-1 C-4 (has Grey sheet value) C-5 (has Grey sheet value) C-6 R-1 The Grey Sheet only lists 3 values: C-4, C-5 & other. I can use "other" to value the two R-1's. How do I value the R-3? How do I value the R-5+? Is there a table/chart somewhere for them? Or am I stuck with searching auction results? And this is just one date for the Classic Head half cents. There are other dates for this set with varieties. And then I'll have the same difficulties with a few other sets. Suggestions will be greatly appreciated.
