Question of copper coins perservation

[fwcrawford]

I have some larger cents that I have cleaned with hydrogen peroxide and they turned out pretty good.
The only thing I notice is that after the coin is dry, you can't make out as much detail.
Is there something that can be applied that will make the coin glossy without leaching out.
I have seen some folks talk using a product called renaissance wax. Does this leave a shiny finish?
Thanks for any help,
Felix

I've found that after soaking in virgin olive oil for a month helps a great deal. I then lay the coins on a paper towel and dab dry. Then I set them in the sun for a couple hours then put them up. I've got some that are several years old and they look very good.

A coin dealer told me to use mineral oil.

I thought about trying the mineral oil and olive oil, but was afraid of leaching problem.
I got this tip and thought I'd try it. If it didn't give me the results I wanted, I could simply wash the glue off of the coins.
I think they turned out pretty good and am happy with the results.
More detail and they are easier to see under various light conditions.
Thanks for the tips guys,
Felix

Renaissance wax was specifically designed for the British Museum metals. It is best applied after the surface is dry and clean. You might want to soak your coins in pure denatured alcohol (ace hardware). Do not use rubbing alcohol. Let dry. This will remove surface water. Next rub a small amount on the coin and rub in with your fingers. After a while it will get a little hard to rub. clean excess with soft cloth or terry towel. This should give you a clean surface with a semi-gloss to glossy surface depending on what you started with. Try on a few cheaper coins and see if you like it.
Costly but a little RW goes a long way.

Just as mark said olive oil works for me.
