Would there be any value above face for 10 consecutive 1988 series $100 bills?? They appear to be uncirculated.
The New York district had the most printed, 448 million! If these were star notes (*) they're far more scarce and valuable as they were the only star notes of the Series 1988 $100 4,480,000 printed. Your notes catalog number in the Friedberg guide is Fr-2172B. Your notes show some of the ink offset from the notes that were stacked on top of them, which commonly occurs after printing and bundling them up. I haven't come across any on Heritage, but completed auctions are good to watch for them. This PMG certified example on eBay didn't sell for $375 and was relisted for $450. Both prices are probably set too high for the market for the note. A Guide Book of US Paper Money (3rd Ed.) gave $175 book price in ChCU, but as guide book prices go, it's usually unrealistic. You could try to sell the set of them in an auction and see how it goes. They might go $125-ish/each, but it's just my guesstimate. Others may chime in with more info or thoughts.
You'll lose more to auction fees than premium you might get over face. It's not worth selling them through an auction house. You might be able to squeak out $105-$110 a piece if you list them on the buy-sell-trade forum.
If you can afford to keep them, keep them. But I wouldn't have them tied up preventing you from buying something else you'd rather have in your collection. Most people at shows won't blink an eye over these notes and may not even want to buy them off you at face....but at some point these should command an easy premium such as the $105-110 range. I say this as someone who is holding onto 5 similar notes/ consecutive from district "I"--Minneapolis. As funkee said, don't attempt anything for auctioning. Last auction I won on eBay, would have saved the seller money by just spending the bills. I actually felt a bit bad for him too
"would have saved the seller money by just spending the bills." That's an oxymoron! One saves nothing by spending. Rather like how merchants tell us to save more by buying more, 'buy four get 1 half-priced'. I think it's not even worth trying to sell to a dealer at a show, just use them to buy what you want to collect at a show and let the dealer decide if they will try to resell the notes themselves.
In this case he would have. I bought 3 $20 bills for the price of $65 and some odd change. When he shipped the bills to me, it cost him $6 to ship the notes to me. eBay charges at least 10% final value fee. There is also a PayPal fee from my payment to him. Had he gone out and bought groceries, a shirt, or anything totaling $60 rather than selling these on eBay I'd say he would have saved money.
Spending money is not saving money, that was the point about your advice that I point out is an oxymoron in statement. I understand what you are trying to say. Not auctioning them would have saved the seller from spending more than the notes were worth, face value. It cost them to sell them. He would not have saved money buying something else with the notes and he would yet to have spent the additional money that the fees cost him. No spending would have saved him the money and he wouldn't have over spent selling them by incurring listing, final auction selling and shipping fees.
