existem 2 tipos dessa moeda? [解決]

vi fotos dessas moedas que o fundo de uma é preto e a outra proof, alguém pode me explicar se existem dois tipos dessas moedas? tenho uma mas ela é a proof espelhada, obrigado.

There's only one type, the proof.  Because of the way the mirror like finish reflects light it may look black or shiny depending on how it's photographed.  The coin page shows both effects.

The problem with taking pictures of proof coins is the mirror-like background is so reflective it's difficult to avoid the reflection of the camera in the picture. Like you can see here:

So people seek for solutions. One of them is making scans in stead of pictures. The result is a black background:

Auction Houses, with better/more expensive equipment/techniques make pictures with a white background:

Natural, black or white, in all cases it's the same mirror-like background.

A very good example how different equipment/technique influences the result you can see here, 2 pictures of the exact same coin:
