Rare Set of Four Teaspoons w/Previously Undocumented Philadelphia Mark

Offered is a very rare set of four Philadelphia coin silver teaspoons, dating to the 1814-25 period, with a mark of R.WILSON in a rectangular punch. This mark is undocumented in Cathy Hollan's "Philadelphia Silversmiths", but is very likely the mark used by Robert Wilson Jr. from the time he began as a silversmith in 1814 until he joined his brother in partnership in 1825 when his father, Robert Wilson, Sr., passed away. Alternatively (but less likely), the mark could have been used by the father in the last few years of his life. In any event, the form and particularly the small drop suggests a date in the 1820s, and there are no other obvious candidates for this mark. The spoons are pretty clearly Philadelphia or Pennsylvania in form. These spoons each have a clear maker's mark (see pics) and each is nicely engraved "RB" in period script. These spoons measure about 5 7/8 inches in length and weigh a total of about 75 grams. Condition overall is very good, with one spoon very slightly out of round and one with some very minor bumps to the bowl; there are no splits or repairs. All in all a great set with a rare mark! Available in pairs for $65 a pair.
