Cook Islands 1981 50 Tene KM#6.4 is missing [επιλυμένο]

Cook Islands 1981 50 Tene sub-type is missing from catalog
The 50 tene used subnumbering for commemorative issues:
KM# 6.1 standard
KM# 6.2 (1728 CAPT. JAMES COOK edge lettering)
KM# 6.3 (FAO issue)
KM# 6.4 ("THE ROYAL WEDDING 29 JULY 1981" - missing)

Since 1981 similar to 1978 with only edge lettering difference, I recommend adding three more entries (1981 Proof, 1981 Matte, 1981 Special) to existing KM#6 page:
https://en.numista.com/catalogue/pieces4162.html

As alternative, this coin should be split up into 3 different coins just like all other denominations (1, 2, 5, 10, 20 cents and 1 dollar). They all have one page for standard issue, one page for CAPT. JAMES COOK commemorative series, and one page for THE ROYAL WEDDING commemoration.

Unfortunately, I cannot modify the page as the years already verified, and I was sent to forum page. Can someone modify this page to reflect all sub-types of this coin?

Thank you!

Mintages as follows:
Matte: 1,000
Special Uncirculated; 1,000
Proof: 9,205

Can someone from Numista team help add above missing dates to 50 Tene coin page?

Thank you for assistance!

I will look on that. :)

Thank you, Jarcek!

I am half asleep now already, so I will try to look on it tommorow. But I think split would be needed.

I added it as date lines to: https://en.numista.com/catalogue/pieces4162.html

Cook Islands needs a referee to sort all of this crazyness, but at least we have it listed.

Agree. Thanks for adding the years.
Solved.
