US 1974 $100 bills were only issued in one series so there were none printed with a letter after the date. Perhaps you're looking at the Federal Reserve District letter or a plate-position indicator. There's more information at the question "What is the value of a 1974 US 100 dollar bill?"

The value of a 1974 $100 bill with the letter "L" on it depends on its condition, rarity, and any unique features it may have. Generally speaking, a circulated 1974 $100 bill with the letter "L" would typically be worth its face value unless it's in exceptional condition or has some rare characteristics. However, if the bill is in uncirculated condition, has unique serial numbers, printing errors, or any other distinguishing features sought after by collectors, its value could be higher. To determine the specific value of your bill, it's best to consult with a professional currency appraiser or collector.
