This web-site may be of interest...  Most of the reproductions are 1933-1945 items, but some are First World War.

Expensive.

Currently, the New Zealand Dollar exchanges for sixty-two USA cents.  

 

I'm not very knowledgeable about the market for "museum-quality" reproductions, or the "not-sure-if-this-is-genuine, so the price is somewhere in-between the market value of an original and a 'high-end' reproduction" situation.  Nonetheless, it is expensive anyway.

 

I know there are militaria enthusiasts on this forum who are much more well-versed in detecting fakes and determining fair market prices for both originals and reproductions (which are honestly advertised as such) than I'll ever be.

 

I'm sure there are many in this forum who would warn anyone off any offering that seems to mix possible originals and suspected fakes.

 

What a bizarre web-page.  Interesting, but strange.
