I have a coffee measuring spoon looks like made of tin with the name Sunshine Coffee on it. I'm just wanting to know when Sunshine Coffee began or just anything about the company

I don't know if it's the same company. But, so far I have found the following:

Langdon Barber Groves  : Sunshine Coffee Company (http://www.lbg.org/sunshine_coffee.html)

It is possible that your measuring spoon may have come from something like is on that site.
