Watch List notes:

Victoria, proof threepence, 1887, young head l., rev. crowned value within date (S.3914D), certified and graded by NGC as Mint State 65
Part of the Portland Collection, the current cataloguers feel the piece is a proof, with a finish totally unlike the standard or Maundy threepence issues, despite it being graded Mint State. A proof issue is unlisted in the Standard Catalogue.
Sold as is, no returns.
