Antique Lot of 7 Single Mother of Pearl Cufflinks

This lot of antique cufflinks includes 7 round mother of pearl cufflinks that look similar, but I don't believe any are actually pairs. The first 4 pictures show different angles with the pieces in the same places. I believe the individual pictures are in order (top row then bottom row), and the only one that has a doubled picture is the 2nd last (4th and 5th last pictures) just to show the condition issue (it is stored sealed in a separate bag). One of the cufflinks is stamped York (top left), but the others are not stamped. Picture 5 also shows an example of the different backings. The pieces have wear throughout, most visible in that 2nd last piece, but the thing that would have the greatest effect on wearability is that they're singles. York cufflink dimensions (they're all similar to this): 13x13mm Total weight: 8.08g Love the piece but not the price? Make an offer!
