Numbered Shaving Mugs are mugs that were not personalized with a person’s name, but instead simply have a number on the side. They are very simple and usually lack much in the way of detail. They were used primarily in hotels or other places where people were passing through so instead of everyone having their own mug, they would have one while they were there. These are very affordable mugs and even a complete set can only carry a small premium, unless they can be linked to an important person or location. Some very busy places had numbered mug sets with numbers over 100, but most numbered sets were likely a set from 20 to 30.
