According to the S/N you supplied, your '89 was produced in 1890.
The '89 was offered in three grades off-the-shelf while higher grades were offered only as special order. The grades differed in barrel material with #! (good) using decarbonized steel, #2(better) using twist steel and #3 (best) using damascus steel.
Without seeing the gun there is no way to determine value. Good luck.
