Antique CJ Allen & Sidney Darwin Sheffield 1893 Etched Silver Faux Ivory "I THINK". This was from an Estate Sale and it is from a bygone era. There are 45 pieces, basically a set for 11. One fork with faux ivory is a bit different and it is missing the large carving knife as well. The 45 pieces with handles weigh about 28.7 ounces. It was bought in 1959 for $100.00 when silver was just 90 cents/ounce. Today silver sells for 22 times that amount, or about $20/ounce. That should make it worth about $2,200, but you decide. *It is 15 lbs packed and because of the cost of shipping, there will be No Returns* On Aug-06-14 at 18:42:36 PDT, seller added the following information: Sellers: Get your own map of past buyers.
