Copper, Ancients, and Mint Errors

[NewMSmatist15]

Hi All,

I was thinking about the posts I see on this forum, what comes up for sale on eBay, and what is mentioned in auction sites and on coin websites and came to the following conclusion. If it isn't old copper (think US large cents or British Colonial currency), ancient (non-PM roman coins for instance), or a Mint Error (some lovely mules, off center strikes, and planchet errors) then people seem to only want to buy, sell, trade, and talk about "silver & gold". 

Of course, the whole idea behind the silver forum is for people interested in silver (and gold), but I've noticed that trend in almost every other aspect of coin collecting. I mention this because some of my favorite coins are base metals and, at least in the US, some copper/bronze cents can go for significant amounts of money depending on condition and mintage figures.

Is the PM market flooded because there is significant variety? speculators? an ideology? easier to collect these coins? 

Just trying to share my love of non-PM currency and find out if I'm simply strange or a part of a larger community that is a bit quieter.
