Hello,
I would probably give $250 to $300 for it. Might drop it back into a military stock as I just like those looks over anything else. Personal preference and I'm in no way saying sporterizing is wrong.
Milsurps can be amazingly precise. Here is my lightly modified Mosin:

A stock 98 with a good bore will be similar.
