As a mint produces more, their costs rise !
Machinery, labour, marketing, tax etc. , and then they get drunk on revenue.
Then add the cost of borrowing to grow.
Someone comes along and notices that they can economise on production costs by just washing the dyes, yeah.
So they paint the process in detergent, creates a milk spot, sales are still up, so who gives a rats ?
Now, it's still a one ouncer, so the purchaser has the metal, but the real customers are peeved.
They, (the mint, manufacturer) don't care, why would they, as the coin is sold, and wages are going up.
You need to stop milk spots ?
Stop supporting them !
