I found these bone pegs just like this, stashed in one side of the wooden box included in photos, with the pale blue paper and handwritten scoring cards folded up and stuck in to the other. And they may just have sat there just like that since the 1870s. 1874 appears on the face of the scoring cards, which look to have been cut down from printed tickets for a lecture/sermon by Charles Jean Marie Loyson (1827–1912), better known by his religious name Père Hyacinthe, a famous French preacher and theologian; pretty cool!). At the top of the folded up sheet of paper is a diagram for a solitaire peg game,.with the positions of the pegs numbered 1-37; it appears whoever was playing was taking it quite seriously, I believe recording their moves from peg to peg, striving to master the game. Interesting as a group, and the pegs themselves are scarce and very lovely things.
Pegs are beautiful and in beautiful condition, c. mid 19th century, I believe whale bone. They vary slightly in length of post, from 7/8" to 1" long, all 1/8" diameter at peg ends. Paper with diagram of peg game and notes shows old fold lines and some tearing as evident. Shipped inside of box in which they were all found. (As noted elsewhere, these pegs precisely fit the holes of the solitaire peg game board I've listed separately today.)
