Any way to determine age of this 10k ring?

[testing123]

Found this in an area that's yielded relics mostly from the 1930s to today. However, it was found in a section that had finds that tended to be more recent - 1960s to date. Is there any rough estimate on age? Not sure if the mark is clear enough. Thanks for any info and happy 4th!

You need a more clear picture of the maker's mark. Using a higher res camera or hold it farther back. We can always zoom in. If you look through some of the old posts you will find a lot of threads with links to gold mark sites on the net.
