The key condition refers to dates and mints of coins that may be common (easy to find) in their lower grade conditions, but in higher grades they are rarer (harder to find) compared to other dates of the same condition. MintState ranks key conditions at the grade levels from MS60 to MS67 based on the coin series on our estimated FMV pricing data.

Is this information available for other coin series?

The key dates and conditions listings where generated using the MintState Coin Value Application. This application is a FREE web based application for all users (no registration required). It has been specifically designed to work on all desktop, tablet and mobile screen resolutions.

Below is the general information for the Coin Value Application.

The Coin Value Application assists users in estimating the Fair Market Value (FMV) of their coin. These estimated values have been formulated using averages from many sources. The values are calculated to estimate a price that is between an average dealer's asking price (retail) and their purchasing price (wholesale). The variance for grade certification is averaged into the FMV calculations.

The application allows the user to specify a coins Denomination and Series and then it generates FMV estimates by year, mint, designation, variety for common grades. Additional filtering and sorting options are available to modify the coins displayed and their order. These options are useful to determine key coin dates and conditions for the selected series.
