To follow up, after checking eBay fees, you may get the highest price selling there, but
you will pay about 5% (final value plus paypal fees) in seller fees.
Check out what the same item is selling for there first.
The fees for smaller items can be over 10% . I was just
checking what a CMX 10 oz bar sells for on eBay and after
fees you would net quite a bit under the Nucleo sales price.
I have bought a lot on eBay, much of it from Bullion Direct when they
were selling there. I did not realize how much the selling costs were.
It does not bother me at all when I am selling a household item, video game etc.
But the bullion is all about profit and loss.
Here is a pretty good eBay cost calculator....
