Just realized I might have some hidden money in my wallet lol. Apparently certain rare 100 dollar bills from specific years can be worth way more than face value? Like some 1966 red seal notes or 2009A series with star markings could fetch $150-$1,175. Same goes for old $2 and $50 bills - the 1928 $2 bills with red seals supposedly go for hundreds. The rarity, condition, and those star serial numbers make all the difference. Never thought to check my old bills before. Anyone actually found a rare 100 dollar bill worth real money? 🤔 Might be worth digging through that drawer of old cash
