I believe this is a good combination of 2 top keywords.
It can serve as a gaming site/gambling etc.
The two keywords are generic enough so with the correct usage, no TM issue.
Reseller price: mid-high $xxx to low $x,xxx
End user Price: high $x,xxx- low-mid $xx,xxx
As this domain has a connection to Casino, it is hard to predict how much the end user may be willing to pay for this domain.
The budget of a local casino or a network of Casinos is generally very high.
So they may be willing to pay even more.
Also, I presume that most of them are unaware of domaining so they will have a hard time to know what is a good price for a domain, this can work in your favor.
The Flippa premium and ultra premium listings won't do the trick here.
Most chances that you will just receive bids from resellers there, which means mid-high $xxx to low $x,xxx or a bit more.
This domain requires a static listing which will wait for the right buyer(end user), like in Sedo.
Furthermore, It would be best if you will utilize a brokerage service for best results.
