on the 1886 coin there are two types. Type 1 where the last feather is between the I and C. Type 2 where the last feather is between the C and A How much difference in value is there? I can't find it in any book including Cherrypickers.
Try the Redbook, it has prices for both varieties. The actual prices may not be completly accurate, but the ratio in each grade is probably close.
