Life-time opportunity. Seller names the price.

Rare

Very likely only found at high-end or specialized auctions. Value is highly subjective.

Scarce

Mostly held by collectors and no surprise to see it priced over $100

Uncommon

Not widely available hence price could vary in a range of $50

Common

Should be easily picked up from local dealers. Often value is below US$20

NR

-

Not rated. So common that should be found easily or not worth to collect
