First estimate of value of my grandfather’s estate at close of probate

The probate document for my paternal grandfather listed the assets in his estate. What is the total value of his estate? Let’s ponder that question.
Values for some items are listed in the probate document. Prices of asset purchases and sales during the time between his death and filing of probate document can be used to estimate other values. For example, I estimated values for livestock at this earlier post.
Here is a summary of the assets:
livestock | 4,508 |
oats and corn | 1,794 |
tractors | 450 |
tractor drawn equipment | 150 |
horses | 400 |
horse drawn equipment | 140 |
other equipment | 180 |
car | 300 |
—– | |
total assets, without $400 liability | 7,922 |
My estimate for the value of the individual items in his estate as listed in the probate filing are accumulated below. I’ll update this analysis later if I can get better definition for value of some assets.
