The 1979 Denver Mint coins, particularly the dollar coins, were produced during a period when the U.S. was experimenting with new coin designs, including the Eisenhower and the Susan B. Anthony dollars. A roll typically contains 50 coins, and these collectibles can be sought after by numismatists, particularly if they exhibit uncirculated conditions or specific mint marks. The Denver Mint's specific production numbers can influence the rarity and value of these coins within the collectible market.
