This is a late 19th century cold water pitcher. Without hallmarks nor being marked sterling it is silver plate. You can have the metal tested for free at a local gold/silver buyer shop. It takes less than a minute and the test is done in front of you. The numbers relate to the mold shape, and they were in-house inventory codes that cannot be used to trace to the maker. Likely American, though without a country of origin stamp or specific country sterling hallmarks, where this is from cannot be definitively stated. Silver plate does not have a precious metal melt down value and thus would sell for significantly less than sterling. As a silver plate pitcher, the high sale average would be $50 - $100. If sterling, $500 - $700.
