corroded zinc pennies

[kingingkunsan]

I rolled them. Had 10 rolls and not one was opened and checked at the bank. But I did pick out the really bad ones and tossed them (about 20). Funny thing, I actually forgot I posted this. But the other day I took a roll of clad dimes I had tumbled. When the cashier opened it she gave me a "are you serious" look. I said what? they are real and still good. Just not as shiny. She took em.

i have had no problems getting the bank to take them from me.
I cleam the coins only in that I remove any excess crud so that will sit flush wjen I roll them.
I then roll the coins and mark each and every roll with
FOR DEPOSIT ONLY.
This is to ensure that they make their way back to the federal reserve where they can look them over and remove any they feel are not up to snuff for distribution.
I bank at Chase and they have had NO problems with me doing this.

I have done some minor hobby metal casting. Zinc melts at a very low temp (approx 600 deg). Alum is a little higher, around 800. I built a small furnace by stacking up some bricks. Using a stainless cup as a crucible, starting a wood fire and blowing air in with a mini shop vac, i easily melt it and pour into a muffin tin. A muffin made from zinc or alum isnt very useful, but its interesting and fun to try.. from what ive read, zinc pennies can even be melted down in an old pot on the stove or a hot plate.

I have tryed to tell them that the banks will take them if you do it right. I have always turned mine in to banks.What happens is people try to turn them without telling the bank, and they give them out as change for stores. Then the bank stops taken them. Flintstone

You can clean your clad very quickly in your tumbler
by using vinegar and salt! They clean up very nicely
with in an hour or less. Then rinse them well if your
concerned about corrosion. The banks won't look
at you with that "are you serious" smirk. Seriously! -)
They will clean up very nicely in less than an hour. Remember
VINEGAR AND SALT in your tumbler, clad only.

I wonder if they would be good to melt down and cast them into bullets?
