Another "Old" Topic: Cleaning

By all means experiment with the above mentioned cleaners on some uncirculated or near so "circulation" coins. After all that is how we learn.

However before you do, you will need a high resolution before and after digital photo to show the effect the cleaning has done.

Coins being micro metalic sculptures require more than just a naked eye evaluation, so we use high magnification to see the true condition of the coin. Unfortunately most cleaning methods under magnification show fine scratches caused by the cleaning process. Some coins are so soft even rubbing the finger across the coin will scratch it, gold for example. Replacing dirt with scratches does not increase it's value.

Keep in mind the toning coins aquire with age is valued by many collectors. It also helps protect the coin. Taking it off is like peeling the protective plastic off new electrical equipment to protect the screen. It is also impossible to bring back the original mint bloom once it has gone.

Using the wrong type of chemical cleaner on the wrong type of metal can cause a nasty reaction and cause the coin to discolour or to tone in an unpleasant manner.

There are coins that do benefit from cleaning though. Ancients that have been burried in the dirt or coins that have vertigris. If left uncleaned the latter will continue to eat a hole into the coin and cause pits. Many of the pros that clean ancients will only use (soak) in distilled water or at the worst olive oil which is slightly acidic.

Anyway, have fun and remember to take high resolution comparison photos, or at least examine the coin under a high power lens before and after.

My opinion is that most of the products you list are not meant to make a coin more collectible, but rather simply to enhance its appearance to collectors who don't know any better.

Many of us on this site have been deceived by coins that were modified chemically or mechanically. I urge you to think carefully about why you think using those products will increase your enjoyment of the hobby.
