Talk Fantasy Football

As there are not that many for sale on Ebay atm I was once again drawn over here for answers.
What are NAF - block dice worth these days?

I just moved house and found I have some extra pairs (dice that belonged to my kids) of the black, orange and silver ones.

If its the original black with gold inlay, I suspect those are worth a reasonable amount still as they're rare. I think the other two might still be available from the NAF (or at least were relatively recently) so it'll be suckers who pay over the price of the NAF subscription for them.

I could be interested in both black and orange, depending on price.
Have you tried sold listings on ebay?
