You could talk about the upcoming drop in silver price.
... along with the upcoming hike in fees for buying real silver.

if you can even find any for sale.

Yep, single digit silver prices. With probably multi-digit fees.

It will be interesting watching as some people try to reintroduce monetary silver, while the industrial uses for silver will jump because of new inventions that NEED silver.
Not enough silver for both...

Or maybe the new industrial use will only use one of the two isotopes of silver...
leaving the other available for coinage.
