U.S. Five cent pieces ("Nickels") should be considered a long-term hedge on inflation. I recently had a gent e-mail me, asking how he could eventually “cash in” on his cache of Nickels. He asked: "Are we to melt them down, or sell them to a collector? How does one obtain their true 7.4 cents [base metal content] value?" My response: Don't expect to cash in for several years. I anticipate that there won't be a large scale speculative market in Nickels until their base metal value ("melt value") exceeds twice their face value ("2X Face"), or perhaps 3X face.
