Wondering to buy a AES Formatum

Hello all, 

I found an old listing that sold an AES Formatum that I wondered if it was real or not. My question is how would I be able to tell if it was real. 

The specs are: 

• 37.4 mm in length
• 22.3 g

Very interested in buying something like this and hoping to get into getting more proto-currency. 

Thanks!

Hello, Since this was moved I am just bumping this up so I could get an answer
