In most cases polishing or cleaning a coin in any way only depreciates the value of it. I would not recommend it but if proper instrments are used a coin can go up in value. but you have to be careful not to scratch or damage the coin in any way. when polishing you do not want to present or change any toning to the coin. be careful what you use.try not to use any curosive chemicals and do not, i repeat do not rub the coin to polish it. It will only rub down the coin.
Short answer: No
Collectors like coins to not be modified at all from their original condition. If you polish a coin, you are actually removing very small amounts of the material and this decreases it's value.
Many coinage metals (like copper and silver) naturally form a patina layer that helps protect against further damage to the coin; by polishing that away, you're just allowing corrosion deeper into the surface of the metal and reducing both the condition and value of the coin. The best advice as to how to polish coins is "Don't."
DO NOT TRY TO POLISH OR CLEAN COINS!! all it does is damage them!
Yes. Don't do it.
You can, but you shouldn't. Polish damages the coins' surface. While they may look nice for a while, the damage will accelerate any future deterioration and reduce the coins' value, often significantly.
No, the 10 is a note.
first you need to find how long it takes Marlise to polish one coin. Then you can multiple that time by the number of coins to be polished. 165 coins/33 minutes = 5 coin every minute . . . . . or . . . . 33 minutes / 165 coins = 1 coin every .2 minutes 270 coins / 5 coins per minute = 54 minutes . . . or . . . 270 coins x .2 minutes per coin = 54 minutes
You should never polish old coins, even if they have turned dark or black.

Cleaning coins is not a good idea, it will damage the coins and lower or destroy the collectible value. Please consult a dealer or collector before the coin are cleaned.
If it is a collectable coin that you are considering selling, it should be left in the same condition you received it in. Cleaning coins generally reduces the value. For general purpose cleaning of coins I put a tiny dab of plain old mint toothpaste on each side of the coin and GENTLY rub it between my fingers. Rinse well and repeat if necessary.
It means that no one has cleaned the coin with a cleaning solution or polish or some other method. Cleaning coins reduces their value.
I do not have my world coins book handy. Polish money to some point is collectible. Especially if it is silver and in a little blue case. You can go to a coin shop or library and get a standard catalog of world coins or you can post your question with a picture on All experts to get a response. I have 3 from 50 to 100zt and they range from $15 to $30 each.
