Hey there Diana, this is a great project, it's funny sometimes just how big steemit is! We actually minted a steem round/coin (well not really coin, but that no big deal) last year in September. I'm surprised we never cross paths or were not aware of each others project, but just for clarity and accuracy this is not the first, but no biggie.

Ours was a 1oz fine silver round. It was a community inspired design, it was also very popular and I'm sure yours will also be. We are actually right now hosting a contest to have design submissions for this years round if you want to check it out here.

Anyways good luck with your project.
