British Monarchs Of The Century 1837-1937-Help Please!

I was able to find plenty of info on Birks Sterling but I was unable to find these exact spoons online. I did find some sets of 6 and 8 with different hallmarks. Do the hallmarks make a difference in price? What do they mean? Also, I was wondering an approximate value of this set. Any help with this would be much appreciated.
Thanks!
