Heard back from Mikimoto - basic form letter - can send to them for a 200.00 examination fee, but nothing on authenticating the tag/seal
Thank you all for your help and interest!

You might find this interesting - another w/ 2 stamps - It's a completed eBay auction

Posting for a acquaintance -
Her mam went to japan in 60's and purchased these - no clasp - perhaps for future fitting?
I understand the Clasp is king id wise (except for fakes)
Question - does these attached tags/stamp/box help verify it's Mikimoto?
Any info I can pass on will be welcome!
