Just found out some of the rarest money bill denominations are literally still floating around in people's wallets lol. Like, you could have a $2 bill from the 1920s worth thousands and not even know it? That's wild. The condition and series year matter way more than I thought. Apparently the 1928 series $2 bills with red seals can go for anywhere from $4 to like $175 if they've been in circulation, but uncirculated ones? Those jump to over $20k. Even the 1953 Red Seal $2 bills hold value - circulated ones in good shape are worth $3-6, but star notes go higher. Got me thinking about those old $50 and $100 bills my grandpa might have stashed somewhere. The 1934 series $50 bills in crisp condition sell for $65-75, and the 1929 Brown Seal $50s can hit $75-100. For $100 bills, the 1966 Red Seal is apparently super rare and worth $135-169. Even newer ones like the 1996 $100 star notes can be worth $150-350 if you find the right collector. The rarest money bill finds seem to be ones with printing errors, unique serial numbers, or that star marking at the end. Like the 1995 $2 Star Notes - most are just face value but some uncirculated ones supposedly go for $500. It's making me want to dig through old drawers and check serial numbers now. Anyone else have old bills tucked away? Worth checking the condition and series before assuming it's just regular cash.
