The item in question is a denomination of United States currency issued in 1953 redeemable for silver bullion at the Treasury Department. It represents a specific series of this currency type printed that year.
This series holds significance for collectors due to its historical context, as it was among the last of its kind issued before the practice of redeeming notes for silver ceased. Its value today stems from its numismatic appeal and intrinsic silver content (though no longer redeemable), depending on its condition and rarity.
