Collectible coins, particularly from the United States, often include specific denominations that are sought after by numismatists. The 50c roll of half dollars from 2005, minted in Philadelphia, is part of the Kennedy half dollar series, which was introduced in 1964. These coins are made of a copper-nickel alloy and feature the iconic profile of President John F. Kennedy. Collectors value these coins for their historical significance, mint marks, and condition, with rolls containing 50 uncirculated examples that can be of particular interest in the collecting community.
