silver coffee set

I have a fb rogers coffee set (cream & sugar bowl included)  that is marked, f.b.rogers silver co. #1200 (coffee pot) 1202 (creamer & sugar bowl).  I am uanble to send a photo, but the set is in really good condition.  No tarnish, chips or blemishes.  Above the fb rogers stamp there is a crown with "trade mark 1883".  I'm not sure when it was bought, I recieved it from my mother-in-law.  She had it some 50-60 years.  Any info you can give would be greatly appreciated.  The coffee pot aslo says silver on copper.  The set has round bases (no feet) and is smooth with a rope-like pattern near & around the top with a rose-like pattern for the cover of the coffee pot and sugar bowl.
