What is the value of a series of 1928 C 5 BILL？Well, the value of a 1928 C 5 BILL can vary quite a bit, ya know? It depends on a bunch of factors like its condition, rarity, and demand among collectors. If it's in pristine condition and is a rare variant, it could be worth a significant amount. But if it's got wear and tear or is a more common version, the value might not be as high. You really need to have it evaluated by an expert or do some serious research to get a precise estimate.
