"925" markings on sterling silver defines it as 92.5% pure silver with 7.25% being a strengthening alloy,usually copper.

A "975" marking can only mean 97.5 % pure silver and indicates a high quality sterling item. It is not often seen,and my guess is that this must be a very old piece or a newer item that uses extra sterling silver in its production.

Either way,if you own a "975",you have a very nice piece of sterling !!
