These are mass produced pieces, the Grape pattern found on these has been used on a great deal of mid 20th century metal tableware, right into the 1980's when the pattern was last in vogue. Most like this were imports, originally having paper or foil labels to indicate the importer and country of origin. What you paid is about what unmarked pieces like this go for at auction or thrift shops.
