I seriously doubt that everyone in tamriel makes their own jugs and pots. Somebody's got to make them and I doubt they'd just give them away for free. Haven't you gone to the store and spent more than a few dollars on a new mug or picher?
Apparently, you haven't gone to the store in Oblivion...^^
They
are worth something when buying them, you
do have to pay for them, but they are not worth anything when selling them, which makes perfect sense, as most traders wouldn't even bother to buy a pitcher if they already sell them.

And about the copper, silver and gold topic:
Tamriel has a money system, and have stopped using the copper, silver and gold for things - just like we do in real life; we use coins that in reality has no value, but has gotten a value to make things simpler than having to walk around with gold pieces.
That is one reason for not using copper, silver and gold.
So, something else should be used, like 1, 10 and 100 value coins for instance, but:
Another thing - World of Warcraft or Dragon Age as example:
I am taking a stroll into a dungeon, and pick up 5 copper. Now, I had 97 copper already, so using this system, I should now have 1 silver and 2 copper, right?
But, where the hell did that silver coin come from?! Did my money just magically transform into something else? 100 copper coins melted into 1 silver coin just like that?
No, that is a system that, even though it's a small feature, it
TOTALLY, and I mean
TOTALLY, breaks the immersion of a game.

Nothing is worthless. People sell air, dirt, some junk. Nothing is worthless.
It made no sense for silverware to be free, I'd rather sell 100 for 5 gold than all of them be worth nothing, because at least then it has some value.
When did silverware become free? What game are you playing?
