Ezra Grizwold, although not a founder of Worthington, Ohio, is considered the first true settler of that town (Source: http://en.wikipedia.org/wiki/Worthington,_Ohio). He moved there in 1803 and ran the local tavern (Source: http://www.worthington.org/about/moneybarter.cfm). His currency is a relic from that time period.
Below are a couple partial sheets of $1 and $2 notes from his tavern, as well as a 25 cent remainder note. Signed copies are usually dated from 1816 - 1819 and are found in denominations of 6.25 cents, 12.5 cents, 25 cents, 50 cents, $1 and $2 (Source: http://www.worthington.org/about/moneybarter.cfm). Compared to most other obsoletes, these notes are quite affordable.
