Thanks for your question.  OSU Extension publishes a timber price report semi-annually.

You will probably need to deliver the product to the mill, so you would use SAWLOG pricing.

I recommend measuring inside bark diameter, and length.  You can estimate board footage using this equation Doyle Log Rule:

[(diameter-4)x(diameter-4) x length]/16= board feet

Below is a directory of woods products companies.  Search for primary manufactures in you part of the state:  https://www.ohiowoodproducts.com/

I would recommend calling the potential buyers ahead to make sure they are interested in what you have to sell.

Yes, I've heard that log prices have increased recently.  I have not seen that report yet.  There is usually a delay of a few months before it is posted.  Kathy Smith (Smith<personal data hidden>) would know when it will be posted. These reports will give a rough estimate based on Doyle log rule and will only be a "ball park estimate"  the prices will vary greatly with log quality.   I recommend calling several potential buyers to get an estimate, but unfortunately you won't know the actual price until they see the logs. Length is very critical. Usually logs need to be 6 or more inches longer than standard lengths due to loss from trimming and checking (eg. 12'6 inches to make a 12 ft. log etc.) 

Good Luck! Sorry that you have had this experience...
