This is a set of seven "1/2's" California fractional tokens sold by the Heritage Society of America, I believe from the late 1960's.  They come in a paper and plastic pack, with a brief description of the issue and a two-page history and order form for additional sets.  The dates and types are: Indian obverses 1852 round, 1852 octagon, 1854 round; Liberty obverses 1853 round, 1855 octagon, 1857 octagon, and 1858 round.  All of them have the California bear and "1/2" on the reverse.  Metal content is listed on the order form as 24K gold-plated, and they are exactly the same type tokens in all the other listings that are selling for $10 to $30 each.  Shipping is $8.00, including tracking, to U.S. addresses only.  Please allow me up to seven days to ship, due to my odd schedule.  Thank you.
