Silver quarters can be purchased through precious metal exchanges such as Gold and Silver, Inc. and APMEX. Other sources are the United States Mint, coin collecting dealerships and individual coin collectors.
If silver value is the main purpose of the buyer, precious metal exchanges and retailers price coins based on metal value and provide a simple method to invest in the commodity. If collector value is the primary purpose, coin dealerships as well as other hobbyists sell their coins primarily for their value as collectibles. The U. S. Mint offers commemorative quarter sets that are minted from pure silver while limiting quantities sold to enhance their value as collectibles as well as the value of the silver.
