Minecraft OG Account?

Moin Moin have a Minecraft 3 character OG account what are the approx value because would like to sell.

Selling Minecraft accounts is illegal and prohibited. Also what is an OG account, never heard of.

OG account 3 characters OG hold 3 letters which you can no longer create you need at least 4 characters to create an account mine has 3 so think that what is worth

Wrong, it is not worth anything because it is invalid and from January it will no longer be used anyway, as you then need a Microsoft account.

And as I said, selling Minecraft accounts is prohibited.
