We have borrowed the system of rarity identification from the book "A Checklist of Islamic Coins" by Stephen Album, since we consider it rather reasonable and appropriate for the pre-Islamic coins as well:
Common - almost always available, but only occasionally in quantity.
Scarce - usually available without long delay, hardly ever in quantity.
Rare - demand outstrips supply, and specimens, when available, are often eagerly sought.
Very Rare - seldom available. Collectors may have to wait years to locate one.
Extremely Rare - almost never available. Few collectors will ever have the chance to acquire these pieces.
On the other hand, we would like to point out that the described coins are encountered very seldomly, and if we have indicated that a coin is not rare, that means it's not rare IN RELATION to other similar coins. Indicated by us definitions of rarity are obviously subjective, some one else could have another opinion, although our valuations are based on many years of experience of working with presented material. To those interested in knowing actual prices for these coins, we can advise to refer to recent auction catalogs or dealers. We do not engage in selling coins.
