Trying to Find ...

Hello People
I have the following gaps in my collection, and wondered whether anyone would have the pieces available or know where I could get them. I am in the UK for postage purposes. The coins/rounds I am after are:
Canadian super maple leaf 1.5 oz 2018
Tokelau Creatures of Myth and Legend Poseidon Reverse Proof and Gilded Proof
Bhutan Lunar Monkey 2016 (I would like a BU version to match my others, but I have never seen one and it may be that only a proof version was produced)
Royal Silver Company Anaconda round

Any help in finding these would be appreciated.

I am sure as the forum progresses and grows you will be able to obtain all of these. Fingers Crossed.
