Post - Reading - Possession

My uncle invited some special (a)   to his house to show them his amazing collections of old books and coins.

One of the most valuable items in his collection is a rare (a)   clock that is over 200 years old.

It is in perfect (a)   because he takes great care of it.

My uncle says this clock is his most valuable (a)   , not because of its money worth

but because it has a lot of (a)   value—it reminds him of his grandfather.

He often asks (a)   to check and confirm the authenticity of his antiques.

I think this clock is my (a)   item in his collection.
