Still holding onto some hoards of European pre-euro .999 nickel coins. I got tons of the stuff laying around. I averaged my purchases to around $4 or just under per pound here. I believe recently it hit record low values. Now looks to be gaining some strength at $5.13. I recall before I began purchasing pure nickel coins it was around $10-$8 per pound. (also has been much higher than that in the past..) I hope there's some potential for this metal in the near future.
I can't imagine hoarding US "nickels". Especially the ones now have much less nickel in them. They are weight wasters.
