We use the English grading system which ranges from Poor – FDC as follows:
Fleur De Coin
Sometimes the grade is modified by the following prefixes:
About (very slightly below the stated grade)
Slightly better than
Grade is between
Obverse grade before and Reverse graded after
All modern proofs are FDC and cased with certificate of authenticity unless stated otherwise.
These coins are contained in a hard plastic case. Most are graded independently by American companies.
