What is the value of a very old spoon marked international sterling mad by spring glory?
I could not tell you an exact value, however I can tell you
International Sterling, contrary to International Silver. is
sterling sliver, which is 92.5% purity. For a Spot calculation. you
would need to weigh the spoon, using a scale that will weigh in
grams. Upon finding out its weight in grams, you then would need to
take the spot price of silver, (Per Troy Ounce), which right now
the spot silver price is 32.35 and divide that by 31.4, which is
the amount of grams in a troy ounce (Note the difference in a USA
ounce, and a Troy oz) . This will leave you with the spot value per
gram, however that is for pure silver. So you can calculate the
Price per gram x weight of spoon, then multiply that by .925 for
the spot value of that sterling silver you have.
Your spoon could have intrinsic value, although most places will
pay about 80 to 85% of spot value, so you will loose about ten
percent due to the buyers cost in melting it down, remember that
your spoon is considered scrap, and that it is 92.5% so if you get
85% of spot, you are doing pretty good.
Good Luck!
