[You're not in trouble, Tonbokiri. he is considering your question but you need to understand the context so you can understand his answer.]

I was being kept at Tokyo National Museum... in the reserves.

[So not even on display.]

I did tell you my value is something humans have ascribed to me. Apparently, this value is such that even displaying me for others to see is considered too delicate... so i was only take out of the reserves for a few weeks at a time, every two or three years, for special exhibitions. The rest of the time, I was locked up in a vault.
