information Most Expensive Numeric Domain Names?

Fellow Domainers,

I am looking for a list of the most expensive numeric domain name sales sold.

I know of:
360.com $17,000,000 2015
55.com $2,300,000 2014
114.com $2,100,000 2013
37.com $1,960,800 2014

Can anybody recommend me a link?

Otherwise shall we build our own list? We need a reference, date and price!

Looking forward to your contributions.

Cheers,
Will
