actually milk spots are a part of the coin that cannot be removed. sometimes drops of water get onto the coin blanks as they make their way to the die press and with so many tons of pressure applied to the blank, anything on it becomes fused to the coin. those water drops which may have some soap (milky color) are forced into the metal.
well I got my milk spots when I touched my coins for the first time, so I think it's a reaction with the natural oil we have on the finger tips, but I think they can be removed with another chemical reaction that also removes the silver which reacted with the finger tip grease…
With coins like this it is possible to clean them in seconds by simply coating them in moist baking soda (sodium bicarbonate) and rubbing them between your fingers. You may wish to use rubber gloves as you will get dry skin from the alkaline mixture. The method described above is more for coins that are coated in something because they have been buried and dug years later. For more stubborn stains it is possible to leave them in the baking soda overnight. Brilliant uncirculated coins may be blackened by the crude silver polishes of yesteryear and may require some cleaning to bring back their full lustre.
The coins look better than their actual condition when they are cleansed and often it will show pits in the coin after cleaning making it worse that's why coin collectors like them tarnished another thing is it shows character of the coin and how much it was used Its mainly a preference I think it makes them look more wore after cleaning but my silver I do clean because they aren't numismatic to me they are an investment and I want them to look good
You might like your coins better cleaned, but if you where to take them to me I wouldn't want them, and most coin dealers wouldn't either. Sure they will buy it for 10%-15% under melt, because melt is all they could get for it. If you like your bullion clean, buy new stuff… Leave our treasured coins alone….. LOL
If the toning is attractive, I keep it. Otherwise I prefer the blast white look for my own collection. If I had a coin with substantial value I'd likely defer to the experts, but my collection is largely for my own enjoyment. Thanks for the video; I really appreciate the investment of your time.
To clean crude and germs off numismatic coins without damaging value: Acetone soak.
To clean cull coins, Flitz polish. Easy and shines brighter than new.
I cleaned some cull silver morgans that way, and they were bright and very nice; however, I started to dislike them. They lost all character when you polish off the tone. The cart wheel mint stamping is gone, and it doesn't reflect light the same way, so I 'restored' toning to them by crushing some boiled eggs and letting them sit with the coins in tupperware for an hour. Lots of tone again. Maybe too much, might have to wait less time next time.
Anyways, yeah, if you got old coins that stink or you feel might be nasty, but you don't want to get rid of the tone, soak them in acetone for an hour. It'll dissolve away organic matter, and will leave the sulfur induced tarnish alone.
The later silver quarters and half dollars clean up the best. A lot didn't spend much time in circulation to get much wear. The older coins that have features worn down from being in circulation a long time don't look as good to me when they are cleaned. The worn but clean look is too contrasting in my opinion. I will clean the older coins that don't have worn down features though.
I also clean my non-numismatic junk coins. I've found that simply giving them a good, bare-handed rub with alcohol-based hand sanitizer works wonders on most of them. I like my Kennedys, Ikes and Roosevelts clean and bright, but I prefer my Mercury dimes and Walking Liberty halves to look "aged", so I leave them alone. Cannot stress enough to make sure what you clean has NO NUMISMATIC VALUE. There's a video where a coin dealer relates a story of a client cleaning an 1850 $20 gold piece. It looks to me like he used "Mothers Mag & Aluminum Polish." The coin sold for around $6100 after cleaning. If he had left it alone, it could have easily fetched $250, 000. Always proceed with caution.
The reason coin collectors don't like cleaned coins is that cleaning coins can cause scratching, which will give it a lower grade, not to mention cleaning coins removes that cartwheel luster that coin collectors like.
There are car collectors who do make a point of keeping the car in as-is condition. It all depends on the rarity of the car, just as with coin collecting and the rarity of the coin. Ultra-rare coins are considered worth far more in original condition than restored condition. Obviously, original-good condition are worth the most. But a slightly tarnished coin is worth more than one that has been cleaned.
The f*** you weather for can make fun of coin collector with toned coins toned coins are the best there is rainbow toning goldstone in wyland colorful turning you don't know anything about Tony f*** you.
