Vintage Leonard Silver Plated Cream & Sugar Set

I’ve had this set for many years but have no recollection of how I came to own them. I’ve never used them. I used to go antiquing frequently so that’s most likely how I came to have them. I hesitated to clean them prior to posting because I’ve read both positive and negative thoughts about doing this. On the bottom I’m able to see “Leonard Silver” (silver plate). Based on my research it seems likely that these are silver plate on copper. I hope this helps! Approximate Dimensions: 3” X 3” Weight 12 Ounces
