Mark, your Grade 2 is from around 1898 and could have been ordered with either Chain Damascus or Crown Steel. The price I believe was $80.00.
As stated by Norm, the serial number block of 90000 is missing so there is no information as to when the exact day/month/year it was made. A very nice shotgun and many are still being used today (after a competent gunsmith determines it safe to shoot with low pressure shells).
