edit to add that here`s the correct rarity scale: http://www.stanford.edu/~clint/coinacro.htm It`s listed under " R# "

Despite the links posted above, my copy of Dr. Sheldon's "Penny Whimsy" includes Sheldon numbers for all varieties of 1793-1814 cents with rariry ratings as (page 44) as follows:
R-1 Common
R-2 Not so common
R-3 Scarce
R-4 Very Scarce (population estimated at 76-200)
R-5 Rare (31-75)
R-6 Very Rare (13-30)
R-7 Extremely Rare (4-12)
R-8 Unique or Nearly Unique (1-3 reported to date)
David Lawrence gave this useful interpretation of Sheldon's rarity ratings in his "Complete Guide to Barber Halves":
R1 Common
R2 A better date. Available at most shows, but in limited quantity.
R3 A tough date. Only a few likely to be found at larger shows.
R4 Scarce. May or may not be available at larger shows.
R5 Very Scarce. Only a few will appear at large shows or auctions in
in a year's time.
R6 Extremely scarce. Almost never available
R7 Rare. Only a few exist.
R8 Unique or almost so.
R# (R1-R8)
Rarity scale. R1 most common; R8 least common. The often used Sheldon scale is:
R8 = 1-3 known (estimated), "Unique or Nearly Unique"
R7 = 4-12 known, "Extremely Rare"
R6 = 13-30 known, "Very Rare"
R5 = 31-75 known, "Rare"
R4 = 76-200 known, "Very Scarce"
R3 = 201-500 known, "Scarce"
R2 = 501-1250 known, "Uncommon"
R1 = over 1251 known, "Common"
Geez, I thought I made that perfectly clear.
R1 common, no premium
R2 common, no premium
R3 common, but you might have to look thru a few coins, no premium unless it's a redbook variety.
R4 not so common. you'll probably cherry-pick most of 'em, but it's gonna take time. if your in a hurry, you might end up paying say 25-50% premium
R5 TOUGH to VERY TOUGH. this is on par w/ what most people call "key dates" (key varieties). you'll pay a premium, say 2x or 3x, maybe 4-5x. you'll only cherry pick 1, MAYBE 2 in a year's time. R5 is where most collectors realize the series suddenly gets difficult
R6 extremely tough, but doable, this would be like a 1901-s quarter in comparison to other barber quarters. you ain't gonna cherry pick it. seldom in dealers "stock", unless he's a specialist, but they'll show up at auction when a collection is dispersed.
R7 not generically available, will only show up at a specialty auction or show. if you want 1, you better get it when you can
R8 locked away in an old collection, you can probably forget about it.
for what it's worth

This site is having some problems, coins I've looked up in the past now have no results showing??????
I nuked the first post out of frustration ( I think justified ). So enough of my nervous breakdown.
