Keeping Nickels?!

When I was younger, I kept every penny I got.
I couldn't afford to keep every nickel or higher...
Just the 'special' ones.

Nowadays, I can afford to keep every copper penny I get,
and for giggles, every nickel I get. I have wised up and
don't keep zincs anymore, unless one catches my attention
with some sort of "eye appeal".

I can sit on coins worth .07 each, at a cost of
.05 each, or I can hoard little dollar coins and
sit on .07 each at the cost of 1.00 each!
Even quarters are worth .07 each!
I'll sit on the nickels...

Edit:
I need to clarify.
I DO NOT hoard change by buying it up!
I just empty my pockets in the evening and sort
the coins into buckets... keepers and circulators.
Just to make it clear that I don't go out and buy
rolls of nickels for keeping! I probably have 15-20
bux in nickels hoarded, and this hoard is about 5 years
old...
