To play in the 99 field you need to know what you are doing. If the gun is correct Not D&T'd, worn but original finnish, correct sights, original butt plate and on and on. Condition is everything.
It sounds more like you were looking at an 1899 B not a 99.
Go to the Savage Collectors thread on 24hourcampfire.com and ask your question. Try and get pictures of it, they will ask you alot of questions it is the only way you can put a value on it.
