Nothing wrong with a humble opinion that is numismatically focused!!! I gave up caring what metals were doing or trying to predict it years ago. Metal prices really do not impact ancient coin prices at all.....a denarius is the size of a dime but a Faustina the Younger denarius, who is one of the most common denarii, sells for at least $35 or so and denarii just go up from there. A nice Caligula one can go for over $2,000!! Those outstripped bullion prices long, long ago. But, regarding silver, you could be correct.......solar panels eat up a decent amount of silver.
