Possible Swedish Hallmark on stick pin

(Lebanon, OR, USA)

Sorry no pics, but I have a stick pin with the following descriptors:

The makers/hallmarks are 2 places: side ways is GGHG or CGHG near the top. script is a little chunky but sort of formal. The 2nd descriptor is lengthways and the bottom is the letter G with a crown on top of that. Crown has 3 points. There is another figure above that but I can't make it out. (almost reminds me of a an outline of a seal.)
