You should know that there are some rules here , among which:
"Post only domains you own or control in the Domain Appraisals Forum."
No offense, but if you have just bought it, pls come back when your name will be in the Registry, as everybody do (or should do).
Now this domain is still regged to a dutch guy, who is the seller I suppose.
P.S. "O" is not exactly a premium letter:imho but at the end it depends on the potential end user, so I guess xxx$ or low xxxx$, depending on buyer interest (Osgo.com was sold in April for 1,050$ at Sedo).
OEJY has not any particular meaning (at least to me), so I would be more in the low xxx$ range.
:wave:
Sorry but I think that "o" is one of the better letters, the real problem of this domain is the "JY" IMO. But I think the fact of be easily pronouceable gives it some value.
