The case is. In last half of 1700 the Old Sheffield Plate (OSP) was invented. OSP was made by mistake. The inventor used a penny when working with silver. When he was finish the copper penny had fastened to the silver. He realized potential and developed the OSP. At these days the value of a silver item = the value of the metal (silver) the Work and craftsmanship = 0. Or very close to 0.
Now one could by a "silver item" OSP for a fraction of the Price of a similar silver item. The silversmith considered this competitive material a danger to their business.
The OSP was a layer of silver on a copper plate. Looked like silver but you could not engrave. When you cut into OSP the copper plate becomes visible.
The silversmiths developed the Deep cut engraving. When cutting Deep into item - you must use silver and not OSP. This pattern of your spoons is one of these patterns.
In Denmark your spoons are named "Empire" empire pattern was developed somewhere late 1700hundreds. I have a fish ladle - checked year 1799. The pattern has been produced until only a few years ago.
Late 1800 electroplating was invented - many af these spoons forks ladles etc. was also made in EP.
Danes are a poor people. we don't have much. So you bought a spoon or fork at a time. A girl whose parents had Money could buy 1 or 2 spoons at a time for their daughter. Or they could get 2 - 4 or 6 at their wedding. Around 1750ties you expect 1 or 2 --- 50 or 100 years later maybe more.
The silver was collected during a life time. Or through 2 or 3 lifetimes. Inherit from your parents and the collecting to get a full set.
During Victorian times - in Denmark late empire - a full set of 12 pieces would be:
Sugar spoons. desert spoons, Soup spoons, lunch forks, dinner forks, 60 pieces.
Knives are very rare. You would use knives of iron - with handle of Wood, stone, bone or porcelain. A silver knife would be to soft. I have some knives - for cheese and for fruit.
To the set would also be grødske - very big ladle (36 to 46 cm) Very common.
Sugar ladle, salt spoons, as mentioned more rare mocha spoon. You could have the spoons instead of coffee spoons. Marmalade spoon, mustard spoon
Here is a mustard spoon approx anno 1810
Here is a set of 12 sugar spoons anno 1806
Regarding the maker. Its him. You had to be a member of the guild. The guild took the initiative to open for a master, but only very seldom. This was a closed World and it was a limited tuber. For a educated silversmith to become master - almost impossible. He had to find a master and Work for him. When the master died a silver Smith could marry the widow and thereby be permitted to go to a test. He would have to make a masterpiece and that would cost several years pay.
In early 1800 the guild system was weakened- and a limited number could Work as a free master. The hallmark would guarantee that the silver Smith was responsible for the silver content 12½ part of 16. But the guardein mark, the city mark - he could not get because he was not a master with citizenship. The tax mark - he could properly get, but he would do his utmost not to have this. Because tax mark = pay tax.
Regarding the master - the book writes he was one of the more skilled fri mestre. But that all, nothing special about him.
Later the guild system disappeared. And a Smith could set up his business. The guild lost influence.
So to get a full set - you would use several years. But pattern same for between 200 and 300 years.
