Extremely rare! In the 1990s the Morgan Sports Car Club Holland issued a series of badge in the shape of the familiar NL plates on cars, with the added club logo. This was legal to use for foreign traveling, instead of the usual plates or stickers. Most were white enamel with black lettering.
A very limited series, no more than a handful, of such badges with golden lettering were issued. This one has been treasured in a collection, so is unused.
A unique opportunity to get a collectors' item!
