If I can buy a whole container (100?) of war nickels for $0.95/ea, melt value is $1.16 today (or thereabouts), there is no reason I shouldn't do it, right?
War nickels are harder to sell for anywhere close to spot because they're only 35% and it's harder to get the silver content out of them. Typically you will usually find war nickles sell in bulk at a substantial discount to melt (40-50%). Plus you have the general problem that most people don't realize silver was ever used in nickels so they may not buy because they think you're lying to them. Those that do know this are also more likely to pay less for the reasons I just stated. That being said, there is a chance you could flip them for what you paid or more, but that chance is not very good. If you're simply looking to stack silver, I would caution against those at that price, and go for at the very least 40% halves or 90%. They're higher cost and higher premium, but they seem to stay more stable for resale later.
Prime Mover gave you the right answer. US coins with less than 90% silver content always sell at a discount, (sometimes a severe discount), to theoretical silver content. Its the same reason why 90% will sell at a discount versus .9999 pure.
Wholesale right now is 90c so that's a very good price. There's no gaurantee that wholesale won't drop relative to melt before you want to sell.
