This is currently posted on eBay and is an altered date 1803 S-260 which has been altered to an 1804. Just check the leaf position under (E)S for a quick confirmation. The seller has been notified. We'll see if he retracts it or not.
Several other leaf positions are wrong for it to be an 1804. The leaf points under ST, AT, M, and RI are all wrong. Position of the berry right of the E in ONE, and the berry below the M are also wrong.
