domain How much do you think those domains worth? - GirlyB.com

[bobchina]

so i just started in domain reselling business and with a low budget to buy a short domain I try as possible to be creative and create some ideas for my domains but I don't know how to calculate it worth .... for example :
GirlyB.com
an Idea of girly brands web site or app
Todapay.com
an idea for payment service
chopgold.com
gold cutting or selling gold service
Ddonation.com
meaning: direct donation an idea for a donation website or app

so please be honest and tell me how much do you think those domains worth?
and how i can calculate that by my self and the future .. thanks

Ddonation.com might be a decent brandable, maybe low X.XXX if you are really lucky. The rest has zero value.
