New York: DuBois calculated the Dollar at NY£ 0.40 ; in 1798 T.D. DuBois charged Lemuel Wells NY£ 2.40 for 12 Tablespoons and NY£ 2.40 for 24 Teaspoons.  The spoon unit price was clearly the same by half, but differed by weight (Ozt.)

Where a 14.6 cm Teaspoon weighed ~0.55 Ozt, a dozen weighed ~6 Ozt.

Where a 23.20 cm DuBois Tablespoon weighed 1.9 Ozt., a dozen weighed 22.8 Ozt.

At assumed weight, workmanship on tablespoons was NY£ 0.1053/Ozt (=$ 0.2631)
At assumed weight, workmanship on teaspoons was NY£ 0.1818/Ozt (=$ 0.4545)
