unfortunately he can only pay you back in 1925 dollars so youll have to take the dime as down payment and get the farmer enrolled in a BNPL

The 01925 dime is worth about US$3 as bullion (see https://news.ycombinator.com/item?id=45907742) even without getting into collectors' value, so a couple of dimes or a quarter will pay for a hamburger. You may just have to stop by a jeweler or a pawn shop first.
