Wells, Fargo & Co., Sacramento, Express, blue oval handstamp canceling on 1853, 3¢ Nesbitt entire to Stockton, with blue company special service printed frank at top, Very Fine. Estimate $200 - 300.
It is speculated that the blue frank designated special carriage on the Sacramento River steamboats, because Wells Fargo's handstamped "Steamboat" markings cease to appear at just the time when the blue franks came into use.
Realized: $350
