You sent me the email letting me know my coins have shipped, but I don’t understand these grades?

The way our system currently lists the grades in the emails are numeric only. A 3-digit grade code beginning with a “1” is a details grade, i.e. 160 would be a 60 with details. The details will be listed on the holder when you receive your coin. At this time, no varieties are listed in the grade email, however we will be adding this feature in the near future. If your coin receives a “90” the graders were unable to grade your coin. If the coin receives an “88” it is considered of questionable authenticity by our grading team.
