My only reliable source at hand is Fjestads' "Blue Book of Gun Values", 28th ed. Text follows:
"12ga., 30 (standard) and 32 in. barrel, black powder only. First Winchester shotgun with a sliding forearm action, first Browning slide action patent, disc. 1897 after run of some 34,050. Note: Chambered for 2 5/8 shells only, damascus barrels were available at extra cost, as were fancy stocks."
Blue Book rates a 90% gun @$675
It goes on to add:
"This gun had limited sales because mechanical weaknesses developed when shooting smokeless powder. Winchester offered a brand new shotgun of the customers choice when they returned their Model 1893."
