Horse drawn farming/gardening plows

These 2 planter or seed plows were found near 3 old 1800 to early 1900's home places that we are tearing down here in the foothills of North Carolina. We have unearthed a lot of OLD stuff from under old sheds that have fallen.  The 3 homeplaces are sitting very far apart on over 300 acres which none have ever had power or plumbing. The owner of the property said he was told that the homes were from a time prior to the 1900's.

Please give me some idea as to what the value of these 2 plows could range from.
