I'm looking for the fonts of the following texts in the picture:
--
IOWA (and) NEBRASKA
--
LANDS
--
At 6 per ct interest and low prices
--

Thanks in advance!

Modern Condensed  Suggeriti da donshottype 
United States  Suggeriti da donshottype 
Britannic  Suggeriti da Heron2001 
Legal Tender  Suggeriti da donshottype 
Grenoble Heavy  Suggeriti da donshottype 

Posters of this type were generally produced by engraving lithography and similar processes that did not incorporate fonts.
There were some fonts from the era that are similar to the various lettering styles in the poster, but they would only approximate the letters.
The phrase _AT 6 PER CT. INTEREST AND LOW PRICES._ can be appoximated by Monotype Modern Condensed

_IOWA NEBRASKA_
No font, but the lettering style -- called concave in the 19th century -- was also used by others

_LANDS_
Similar to the U.S. Dollar lettering, made into a font called United States by Typearound

For Iowa and Nebraska

NOT THE FONT - just a substitute.

_LANDS_
Another similar

EDITED:
_IOWA NEBRASKA_
Heron2001's suggestion of Britannic is a good substitute.
All it lacks is the concave stroke feature of the straight strokes in the image.

EDITED:
_IOWA NEBRASKA_
Grenoble TS Heavy is almost identical to Britannic Ultra but has more contrast in some of the curved strokes and thus is perhaps a trifle closer to the image.
