Morgan Silver Quadruple Plate

I have a quadruple plate, coffee/tea service labeled, Morgan, silver company, Boston, quadruple plate , 200. On the Internet I was able to find that this company was active for only 10 years, 1882-1892. It does have some minor dents, but it’s in very good condition otherwise The tray appears to be a bit worn because there’s what appears to be copper metal showing through the engraving. Wondering about both appraisal and whether it can/should be sold or donated to a museum, etc. The tray is actually not the same set, has a different mark on it (last 2 photos.)
