My Collection: Coins (not unlocking)

Noticed that there are a number of new coins within the Collection pages. I believe that my account meets the requirements for unlocking the new additions, as I have all current cards unlocked, yet they still remain unavailable.

Wondering if this is known or intended.

Thanks.

Found this in the known bug log:

[Added 11/29] Some Collectible Coins for old expansions (Engineer’s Coin, Naxxramas Coin, Gallant Coin, Explorer’s Coin), are incorrectly visible in the Collection Manager. They’re still in-development and can’t be earned right now. They will be earnable once they are ready. The team is investigating a solution to their early appearance.

Thanks. Was about to go spelunking for an answer.

I have same bug and some players have these coins already

i have unlocked a golden jade-coulored coin in the middle and in my collection is nothing…. does that mean i get nothing for that….
