IDN Sales History, Parking and Sales Platform

Dear Members,

I have few questions and i would appreciate if someone can help me out.

1) Where can i check past IDN sales?
2) Which domain parking works well for IDNs?
3) How to evaluate end-user value/reseller value for IDN domains?
4) Where do you sell your IDNs- Sedo/GoDaddy/Flippa etc?

Regards,
Manish
