Date and Age of Wine Bottle Coaster?

Would anyone be able to help me date and place this wine bottle coaster?


Apologies to hijacking this thread.i cant seem to post independently.

This is an electroplate mark and, although we can’t be 100% certain, it is very likely to be a mark of Thomas Wilkinson & Co of Birmingham. Dating electroplate can be a bit of a black art but I can say with confidence that this is a 19th century mark.
