Antique c. 1860 Pure Coin Silver Teaspoon, monogrammed A. D. Woodruff. Hallmarked with initials M.F. & C.H.S, and also an H & S Star of David - the mark of David Hotchkiss and Andrew B Schreuder of Syracuse, NY. 

Weight is 16 grams, measured on my kitchen digital scale. 

There is wear consistent with age and usage. I have three of these spoons - there are some dings in the bowls of all. The best of them will be shipped to the first buyer. Please see photos.
