99 Rowena Tokens, each collectible worth 1 Token, maximum 14 tokens per game day... Minimum 9 hours of worth/waiting.

Oh, multiplied by 3, of course.

Why does mining have to be so grindy, just to get items that won't be sought after a patch later? And the worst part is; if you don't keep up with each patch, you fall behind and then there's no point in even trying to catch up if you value your time.
