Please make a Japan Trade Dollar silver set registry! 1 1

[Rinkai銀竜斎]

Dear NGC staff, Hello.

I have a request.
I can't register the set registry of Japanese Trade Dollar silver.
It was manufactured only for 3 years, 1877, 1987, and 1910.
There is also a prototype coin in 1874.
Please create a set registry.
I'm not good at English, so I don't know if I can write it well, but please help me!
Best regards
