Without a photo, it's difficult to know which kind you have. If it's very ornate, with a raised fruit motif in the bowl of the spoon, most likely it's a berry sugar spoon. I believe these originate from the UK.
It probably means that you have a spoon with a maker's hallmark on it. I'm not familiar with that particular hallmark but it's likely silver or at least sliver plated.
Generally, pure silver is much heavier than a silver plated object. Pure silver objects such as spoons will also have a stamp somewhere on it that will say "925" or "925/1000." This shows you that the spoon has a silver content of 92.5 percent. Silver plated objects will not have this stamp.
The 925 hallmark is indicative of 92.5% Sterling Silver.
The Silver Spoon was created in 1934.
