~~~ UK material we would be in good shape... and, yes, sometimes it takes many years of waiting in order to see if any additional pieces of rare material surface.

In the case of my Sporting Club find, I consider myself lucky that in 15 years not an additional piece popped up -- and even up to a few years ago, the 3-piece set commanded well over the original selling price; $1000 more.

BTW, the £1000 plaque still remains the rarest w/ only 3 pieces known...
... and another rare bird is the oval £10.000 CHC piece with only one known still after all these years.

One final note.... KEEP POSTING; we need all the info there is to be had.

Thanks.
