A Superb Ca. 1780s Birdback Tablespoon Marked "I*M" Twice

Offered is an exceptionally fine and earlier (circa 1780-90) American coin silver pictureback tablespoon, marked I*M or I.M twice without serifs. This birdback tablespoon has clear maker's marks and a very well preserved bird, with an unusual and scarce style of bird, facing right with the olive sprig rising over and behind the head. This is sometimes seen with Boston birdbacks, but on the whole this is probably a Pennsylvania (most likely Philadelphia) or New Jersey birdback. It could be by one of the known makers from Philadelphia, and the die for the bird is certainly a sophisticated example - however, this feels like it may either be a Lancaster piece, or perhaps Trenton. In any event, it is superb, with a pronounced midrib and an unworn, egg-shaped bowl. There is no monogram and no sign of erasure. This piece measures about 9 inches in length and weighs 60 grams. Condition is excellent, with minimal wear and only one shallow dimple to the bowl - no splits or repairs. All in all a very fine piece!
