rarity scale: a system used to rate the rarity of a coin, usually from 1 to 10, with 1 being common and 10 being unique.
raw: a coin that has not been certified. Warning: there could be a reason why! ...

Rarity Scale
A convention for designating the rarity of a coin, such as Sheldon's system (with values such as R1 for common pieces and R6 for extremely rare specimens) and the Universal Rarity Scale invented by Alan Herbert (with designations such as URS3). The often used Sheldon scale is: ...

Rarity Scale
Used primarily in PATTERN coinage and early cents, it is used to estimate the surviving POPULATION of a coin. Specifically: ...

Rarity Scale/Sheldon Scale - The scale by which rarity in terms of known or likely known specimens of a particular coin exist.

A system for designating the relative number of specimens known to exist. The two most commonly used in numismatics are Sheldon's scale (ranging from R1 for common pieces to R8 for those that are unique or nearly so) and the Universal ~ developed by Q.

A convention for designating the relative rarity of a coin.
A former basic monetary unit of Spain and Spanish colonies.

A numerical-rating system used to quantify rarity. One example is the Universal ~.

Rome ~ for Republican bronze and much more. From Andrew McCabe. Ashmolean Museum's database of provincial coinage from the Antonine era. A truly magnificent resource. I hope they expand this to earlier periods - like Trajan's reign for example.

The ~ introduced in 1949 in Early American Cents.
The emblem used on certain issues that has horizontal and vertical lines in a shield shape. These are first found in the center of the heraldic eagle and on each succeeding eagle until the end of the Barber quarter series in 1916.

Many ~s have been devised for specific coin series or other areas of numismatics. One of the best known is the Sheldon Scale originally developed for early large cent varieties.

Note: The ~ here includes three main ratings from C (common), to S (scarce), to R (rare). Within each rating numbers from 1-10 are may be used to indicate increasing degrees of rarity with 1 the most common and 10 the least common.

Universal ~
A collectibles rarity information scale developed in 1998 by 21 major collectibles experts in order to both define rarity within their individual markets and allow collectors and dealers from different collectibles markets to more easily communicate with one another.

Universal ~-A scale that measure's degree of rarity. A 10 point, ascending scale (higher number corresponds to increased rarity) that goes from UR1-readily available to UR10 - unique (literally one of a kind).

The Universal ~

It is quite obvious from the above that another scale was desperately needed by the hobby for indicating rarity of all coins. Leave it to Q. David Bowers to recognize the need, and develop a method that could be used for any series, and any rarity.

~. 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" ...

rarity An infrequently encountered or available item; the number of surviving specimens of a particular issue, as may be indicated by a ~ index.

Comments: This is a fairly rare coin which Peters assigns as a R6 on the ~, meaning 10-20 examples survive, although August and Sarrafian have recently revised this to an R5 (in their scale, 17-32 examples) in lower grades and quite rare in grades of very fine of higher.

Sheldon also designed a ~ based on known populations of a certain die pairing. All large cents sold or auctioned by Superior Galleries are attributed by die variety, thus a typical attribution will read, 1794 S-30, R.

no more than 75 to earn that designation on the Sheldon ~), but with these coins becoming not affordable for the general collection coins with much higher mintages are becoming "rare coin investments".
Rarity of the coin has a huge affect on rare coin value.

These Pattern coins ('Trial Strikes') were invariably the first coins off the dies and are eagerly sought by many of today's collectors. Most of the gold denominations are typically high R-7's and R-8's on the ~, meaning there were only 2-4 made. So, what's so 'common' about that?
