appraise tinker.[co].[uk] - value?

[ExR]

I may be looking to sell the domain tinker.[co].[uk] with rights to tinker.[uk]. The domain is a dictionary word and brandable.

Does anyone know what I should expect for it? If anyone has any recommendations on how best to promote it for sale, that would be great. I have used Sedo previously but would rather not use them again.

Thank you!
