Sorry, not the answer I was expected. I am not interested in creating a Custom NGC Registry Set. I am wanting to expand the number of Registry Sets for Japan and hopefully increase interest from other collectors.
Earlier, I requested a coin be added to the 100 Yen Type Set, 1957-Date, Mint State Set. It was incorrectly added to slot #10: 1990-DATE CHERRY BLOSSOM. I have corrected it by removing the coin from that slot. In light of that incorrect action, I am suggesting three changes be made to the 100 Yen Type Set, 1957-Date, Mint State Set. First, Slot #10: 1990-2019 CHERRY BLOSSOM. That is the Heisei era/period which ended in 2019. Second, the addition of slot #11 2019 Cherry Blossom. This is the first year of the Raiwa era/period. Finally, the addition of slot #12: 2020 - DATE Cherry Blossom. This is the continuation of the Reiwa era/period coinage.
Thank you for your attention,
M Wayne
