Old markings on tea set?

Question

Hi, I just recently purchased a very old tea set it reads "silver in copper" It has 3 different markings on the bottom of each one, a "crown" like an "S" with a line through it, An a "shield". Does anyone have any idea how I can look this up to see what its worth online, or just to do more research on it? Let me know, Thanks!

Antiquitey markings is a college course at many

  universities.  This requires an auction house full license

  to become approved to trade.  For personal items the

   sites that are kindred to your habitat location must

   be associated with the auction, shop, or shipping industry

   to really have sensible quotes to show.  Try this site
