Tribune Bicycles were manufactured by The Black Mfg. Company in Erie PA - 1894 through 1902 model years.
The Tribune in second photo above is a 1899 Model 40 which is their less expensive model offered that year. General bicycle values are based on make, model, completeness and condition. More close up photos of this Tribune and your other one would help understand their condition. There will be a serial number on the bottom of the frame under the crank set. I would be interested to know what it is if you can read it. Should be between 35000 and 50000.
