I hope you've been saving your silver quarters. Look at what the price of the metal has done for the past 5 years. Gold has done even better, so there's room for silver to run if the 20th century average ratio of gold/silver price (47 to 1) is again achieved.

Silver today was over $26 an ounce. If you had saved common silver coins in the 50's and early 60's, your $100 in pocket change would today have a silver value of nearly $2,000!

Casino silver premium tokens and earlier high-denom slot tokens also contain significant silver, so this is not completely an off-topic post.
