This is the only solid silver coaster of this type in the universe (unless there is a parallel one.)
I designed and manufactured the tooling and made just one sample.
It is 110-millimetre diameter by .5 thick and has been hallmarked at the assay office in Birmingham.
The case made from oak and is branded with the same Logo.
