Collector coins, particularly from the United States, include a variety of denominations and series, such as the Jefferson Nickel. The Jefferson Nickel, issued since 1938, is a five-cent coin featuring Thomas Jefferson's profile on the obverse and Monticello on the reverse. Coins minted in 1967 have specific characteristics, including variations from the Philadelphia Mint, which often hold appeal for numismatists. The Half Dime, a denomination no longer in circulation, was produced in various forms prior to its discontinuation and is also sought after by collectors.
