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 each, of such badges with golden or copper lettering and background were issued.
 
These all ended up with serious collectors, so were treasured.
 
A unique opportunity to get a collectors' item!
