I am new to this sight but I have been detecting in louisiana for over twenty five years. Here we call them pickers checks. I have several varieties from louisiana and mississippi. They were stamped out by farmers and given to pickers of vegetablels and other produce. 2.5 for two and a half pints of berries or with beans or peppers or other vegetables two and a half bushels. some have farmers name or initials on them and some do not. there are also varieties that were printed on paper tickets down here that are rare as well. A lot of people down here find small round ones with initials on them and mistake them for maverick tokens because they are coin sized instead of large. They were usually stamed out of whatever was cheapest for the farmer to get. some copper, some are brass, some are aluminum, i,ve even seen a lead one found. some of the tags from here have louisiana stamped in them and i have seen two stamped with mississippi on them. some have nothins but the amount of produce being recieved such as 2.5 or 2 or 1.5 and nothing else. Most times these are hard to identify unless you find one of the fancier ones that has the farmers whol;e name stamped into it and these are very rare and usually somewhat valuable. especialy the coin types.
