Unfortunately war nickels do not bring a premium, the alloy is weird, and when refining them the alloy causes problems, Also, with the current ban on melting pennies and nickels war nickels are currently included in that category, So people who have them are stuck with them, and most people dont go out of there way to buy them. Its not worth the risk to refine them, and its not an alloy that is usable for anything but what they are.
most refiners wont touch a silver alloy under 90% if they can help it. Again, it has to do with the processing, Alloys of lesser amounts end up costing more to refine, and process.
In order to make any money off them you would need tens of thousands at that price to make it worth while. And most basic refiners charge at least $75 to do silver in any amount.
Unless you can clear at least $100 to $300 profit after fees/ shipping etc. Or find people willing to buy them, or if your keeping them for yourself.
never buy anything you cant turn the next day for a profit is how I operate

I would pass
