I have a common share certificate of 50 shares for geheral household utilities company in 1938,?

Question

whwrere do i take it to find its worth?

Answer 1

That was pretty much the year the company shut down.  It was founded in '33 and its last model year of radio was the '38, which was built back in '37.  It is very likely completely worthless, other than for nostalgic purposes, or having something old to look at.

Answer 2

If you have not had any communication from the company, they have probably closed down or been taken over. Contact a stock broker or bank manager and find out what  happened and if the certificate has any value.
