Silver supply and demand disconnect

The US mint is rationing and/or not making any silver eagles due to a “lack of blanks”. They have also recently announced that they are not selling/making 1 oz gold eagles due to a lack of blanks.

I ordered some silver from a mint on July 25 - the expected delivery is late October. I am trying to order more today and I can’t even get through to them.

Silver bullion is going for about $18 - $20 per ounce on ebay (including shipping).

Yet the official spot price of silver is $13.35. Doesn’t make much sense to me.

Edit: I FINALLY got through to a sales person at the mint. I asked about an accounting issue and she told me “poor so and so has been so busy, she got 400 checks in just one day”
