Want to give a follow up on this token. I have researched multiple places. Picker checks were used in Anne Arundel County, MD from about 1880 to 1930 predominantly in northern AACO which is just south of Baltimore and in the area currently occupied by BWI Airport and surrounding communities. They were also used in mid Atlantic states and other scattered areas (found some in Louisiana). Besides the online bit that Bramblefind posted (thanks very much for the lead) the best resource for the use and a listing of the AACO usage is a book by local historian Willard Mumford called Strawberries, Peas & Beans, Truck Farming in Anne Arundel County. It is available at the Ann Arrundell County Historical Society-
Ann Arrundell County Historical Society In the neighborhood of 400 farms and 1500 different picker checks have been identified. Different sizes and shapes denoting what was picked and numbers representing how many baskets or bushels or whatever. Checks are still collected by some folks. Many have been turned into jewelry -necklaces, bracelets, ear rings etc. Shapes include clover, diamond, oblong, octagonal, round, scalloped, shield, square and sawtoothed. Various edge millings. Most are brass but some are iron, Aluminum (later ones) iron, copper and fiber.
As best I can find speaking with Mumford and the lady I mentioned in my post Feb 27, no one has ever seen a check like the one I found. There has only one been seen with the initials BG on it but it has no value (number) stamped. One farm was located about 20 miles from me and is not likely. The other was located in Annapolis at the edge of what was Parole Camp #3 which was a prisoner of war Parole camp in the CW. The farm is identified on the 1878 Anne Arundel county map and was run by Benjamin Garner. He stopped taking picker checks in 1894 (ad in local paper). We know the location of my house was occupied at that time and as was only a but 2 miles away, suspect it came from that farm. A neat find as it is unique (so far anyway). Probably donate it to the historical society at some point.
Sorry for the long post but thought a few might be interested in case you find something similar.
