A#1,
Do not sell that bill until you have researched it thoroughly!! It's worth a small fortune !!
I vote it for BANNER right now; I doubt such a bill has even been seen on TNet before; at least none has ever been reported as found, such as yours.
Collectors look for certain patterns that include solids (every digit the same), such as 11111111; ladders(counting up or down), such as 12345678; lows, 00000100 or lower; highs, 99999900 or higher; radars (same backwards and forwards), such as 13466431; repeaters (second half same as first half), such as 12791279; super repeaters (pair of numbers repeated four times); double quads, such as 55553333, seven in a row and seven of a kind.
To collectors, yours is the rarest kind (and most sought after) bill; a 'solid' of 4s. If I had that bill I'd submit a copy to Heritage Auctions for their suggested opening price and estimated value range; it's in the thousands !!
