25th top anniversary, napkin rings dated 1887 to 1912, monograms of couple, 110 years old, great gift for today

These sterling napkin rings are in beautiful condition, and it is hard to take in that they marked the anniversary 110 years ago. Napkin rings were a part of daily life when ironing was difficult so it made sense to use them more than once. And how fitting to mark a special occasion.

In perfect round, I could not photograph the sterling incised but will try again in different light . It is there. The dates are 1887 to 1912, and they appear on either side of the initials BLP and top BJB. Isn't it amazing they have stayed side by side for 110 years?
They are 1.5 inches in diameter and .75 inches in height.
