Ā That is more than likely the purity of the silver, though the most common purity marks are 800, 925, 950, and 999 (meaning 80%, 92.5%, 95%, and 99.9% pure silver) (I wonder if it may be an "800" with any combination of wear/scratches/marks on the zeros that make them appear to be other numbers?). Ā It could also be a pattern mark, but it's hard to say without a pic.

Without any other markings being present I'd say it's just a mold/model number.
