On a somewhat interesting/historical note, this is what Lewis and Clark took on their expedition for trade (or presents) with Native Americans:
12 Dozen pocket mirrors
4,600 Sewing needles
144 Small scissors
10 Pounds (4.5 kilograms) of sewing thread
Silk ribbons
Ivory combs
Handkerchiefs
Yards of bright-colored cloth
130 Rolls of tobacco
Tomahawks that doubled as pipes
288 Knives
8 Brass kettles
Vermilion face paint
20 Pounds (9 kilograms) of assorted beads, mostly blue
5 Pounds (2 kilograms) of small, white, glass beads
288 Brass thimbles
Armbands
Ear trinkets
Not all that bad of a list even for today, especially considering this was a list from 200 some years ago.
