A collection of one example of each design type in a coin series Type.

a more common collecting model in numismatics

a collection of coins based on denomination. For example, a nickel type set would contain one of each of the four types of nickels that the United States Mint has produced.

some times clients provide artwork (logos, sample ads, etc.) that use fonts that USM designers do not have on their computers. In these cases USM will offer to find a similar font and "type set" as close to the sample as possible.
