Cleaning Mexican Libertads

[Coolsmp]

Picked these old Libertads up. A bit dirty.. looks like rust. Any tips on cleaning them up?????

Might look like rust but they are 999 silver so just grime.
Lots of methods for cleaning previously ( and very recently ) discussed on this forum.
Assuming they are typical well handled (i.e. not pristine ) condition to start with, I would wash in soapy hot water with a cotton wool ball to scrub.
If that fails then use silver polish or e-Zest dip.

And what about this? Looks amazing.
Anybody any experience? The disclaimer talks about not doing it to silver that has any value above spot.

Looks like it could be standard silver tarnish, the cleaning of which is well understood. For the record, silver tarnish is extremely common on pure silver (999 or 9999).

You're getting bad advice so far. Never use dips or silver cleaning products on bullion. Try soap and water first. If it's still there it's probably tarnish. Then use the aluminum foil and baking soda method:

• Boil some water.
• Line a plastic or glass bowl with aluminum foil, or use a disposable aluminum foil pan (pie tart pans and single-serving meatloaf pans are ideal)
• Toss in a tablespoon of baking soda, and a teaspoon of salt (preferably pure salt if you have it – this would be canning and pickling salt). Then pour in the water.
• Place one coin in, let it rest on the aluminum foil at bottom. Flip it after about 20 seconds, wait another 20, then remove. Your tarnish will be gone.
• Rinse with water, towel dry, let them air out for a bit before putting them in capsules or Ziploc snack bags (smaller than sandwich bags – ideal).

you can try rubbing some ketchup with your fingers. This isn't a joke. It worked for me on the same type of Libertads.
