Father And Daughters Cleaning Expedition

LOL, They got good eyes Zach! They picked out the ones I would have thought you'd have the best luck with! They just may have left you with the slugs! Good Luck, looks like fun, may have to try it if I get bored of the other stuff!

That's awesome!

What are the steps you have planned (or have already done) for the cleaning process?

Numbers 2 and 12 clearly have bronze disease
Some of the others likely too
If you find parts of the coins to be "crumbly" around the edges and have greenish areas within the coin is likely in the last stages of life.
Some of the larger volume coin dealers will sell you lots of semi cleaned coins which might give you more satisfaction

I realize you are doing this as a first experiment with the kids and you will learn something from it
But you might consider moving up a few grades on the next attempt

It isn't easy to clean coins
But with the right coins it can be very rewarding to see a coin restored to much of its former beauty

Don't be afraid to ask opinions here before you buy more coins
Many of us have a few nuggets of wisdom and are willing to help

Well hopefully we can salvage these may not be the prettiest but all we got at the moment. Thanks for letting me know about bronze disease. Had no idea.
