I recently came across a patent of my Uncle's from 1954, and I'm wondering whether it could be worth anything today.

I believe it has to do with time navigation in the ocean.

How can I find out whether it's worth anything? The patent number is US2694522.

A patent is valid for 20 years (17 then) today assuming renewal fees are paid

Now this patent may be worth something in a nice frame

As an expired patent it has no value. In 1956 patents had a term of 17 years from the date of grant, and maintenance fees did not exist in the US until 1980 or so. Today patents terminate 20 years after the day of the application filing. If a patent took 3 years before being granted, it would end up being in-force for 17 years.
