Circular hard plastic cases reduce a coin's exposure to physical and environmental damage and are a good storage solution for gold coins such as the Liberty. Sending the coins to a numismatic grading service provides even greater protection. After grading the coins, the inspector seals each one in a heavy, tamper-resistant plastic slab labelled with a certification of the coin's authenticity and condition. Plastic slabs prevent direct handling of the coin, but are ideal for long-term storage.
Regardless of the protective casing, proper coin storage requires a constant moderate temperature and low humidity levels. Handling a coin outside of its case only when absolutely necessary is ideal, as blemishes and evidence of cleaning can reduce a coin's value. Owners should always handle coins with clean hands and hold them by their edges, not their faces.
Even Liberty coins in poor condition are highly valuable, as all gold and silver coins have a minimum or "melt" value based on their precious metal content. For example, a $2.50 Liberty coin contains 0.12 ounces of gold, so its melt value in 2015, as of September, ranged between $131.80 and $154.41. In most cases, the melt value accounts for the majority of a gold coin's resale price. However, Liberty coins with rare dates fetch a high premium over their melt value. As of September 2015, an 1881 $2.50 Liberty in very fine condition has a potential resale price of $1,445.
