Hints and thoughts about using The FoxLair True Rarity Scale:

• This rarity scale is a guide developed by the author for his personal use; he is sharing with you.

• The single most important part of the scale is the number of coins available in the market.

• This rarity scale is only as good as the data known about each DAM or Date/Assayer/Mintmark.

• Grading by individuals is subjective and varies greatly.

• A single coin graded by different people can normally vary by as much as two grades. 

Collectable Grades used by the author:

1. GEM: The Perfect Coin full strike, perfect centering, full luster, Problem Free no hairlines or field marks 

2. Unc: (Mint State) No Signs of Wear, Lustrous, but Strike and Luster can vary by mint & year         

3. aUnc: (almost Uncirculated) Signs of handling or circulation on high spots and fields, much mint luster

4. XF: (Extra Fine) Noticeable wear on high points, generally has light field handling and bag marks

5. VF: (Very Fine) Moderate to heavy wear on high points, many field marks, dings & rim bruises normal

6. Fine: (Fine) Heavy wear across entire coin, legends are all readable, but worn

7. VG: (Very Good) Central features & legends are disappearing, but legends are still readable
