Blue Ink

In 1928 the Treasury adopted standard colors to distinguish the four types of bills that were then in circulation. A blue seal and serial numbers identify a bill as a silver certificate, a banknote that could be exchanged for an equivalent amount of silver. Silver certificates were discontinued for $5 and $10 bills with the 1953 series and $1 bills with the 1957 series. Redemption for silver metal was halted in 1968.

Serial Numbers

A bill's serial number is a counter and a security feature. In most cases it doesn't affect a bill's value or help to identify it. Some collectors specialize in bills with low serial numbers (e.g. 00000005) or unusual patterns (12344321) so these can bring above-average prices.

DISCLAIMER: The values quoted are market averages as of the date shown, but may be different for an individual bill due to variations in quality and other factors. Also the wholesale (buying) price of a bill will be less than the selling (retail) price. A reputable currency dealer will be able to give a more accurate valuation based on an in-person inspection.
Current retail is $5 to $10 depending on how worn the bill is.
