This is a nice set with the initials of “K K”. The marking on back is L. Bauman. This set is from the late 1800’s and are in very good condition for their age. They have a few dings but you will usually get that due to how thin the coin silver is. Sterling silver normally contains more pure silver than coin silver, although the general difference between coin and sterling silver is fairly small. Check out the pictures on this great looking set. There is lots of reflections in these pictures.
