Scrip from New Orleans. Here’s some other examples; https://currency.ha.com/c/search-re...les-Desc&Nty=1&Ntt=Magee+&+George&limitTo=all
Says "Will pay bearer one dollar, on demand, in current funds, when presented in sums of Twenty Dollars." Nice looking piece. Not quite sure how to interpret the redemption though. - get one dollar when you bring in 20 of these? - get 20 dollars, but you have to redeem 20 at a time?
