Free, I understand about those old coins. Still trying to find a good map of an old oil boom town 9 mi. W of me. Had 2 H.S., 6 grade schools, and I forgot how many boarding houses. The main street had a wood boardwalk 3 mi. LONG. There's been silver $1's, IH's, and at least one $5 gold. It had a pop of about 30,000 in mid to late 20's and was nation's largest casing head gas plant.
