Spotting cleaned and dipped coins

Spotting Cleaned and Dipped Coins


In the coin market of today you need to be aware of a great deal of factors if you intend to be a successful collector, no matchless likes getting the wool pulled over their eyes. So it is always good to be aware of techniques and processes which people may use to alter the appearance of a coin .

unfortunately it has been known for collectors to fall on bad fortune and confrontation less scrupulous or uninformed sellers and pay over the ask monetary value for something that appears to look glistening and nice, or of value and merit, has the appearance of great luster and shade, but to then find out that the purchase is overvalued and the mint has been tampered with .

now merely to make it clear, it may be particularly appealing for a collector to wish to bring a mint bet on to its original glory, but I would rarely recommend that you do this. Dipping and clean coins is a dangerous game and will result in devaluation. There is a huge price discrepancy between an original coin that has not been touched and one that has been altered in any means !
few circumstances warrant the clean of a coin and I will list those that do late .

Coins cleaned with a fabric or polished can lose anything from 20 % to 25 % in value if not more ! Be warned !

typical methods of clean are as follows :
Using alloy polishes and cleaners, toothpaste, acidic condiments, baking sodium carbonate, soap, scrubbing with any harsh fabric or rag or wizzed ( tooled ) using hand held electronic devices such as a dremel. Bleaching, greasing and oiling. Laser houseclean and supersonic cleanse .

nowadays you may be asking yourself why this is then bad, what could be wrong with such processes ?
Are we not attracted to all that glitters and shines ?

When a coin is cleaned the summons removes its natural patina arsenic well as removing layers of metallic element. This basically damages the coin beyond repair ! What you take away you can never give back !

Patina :
To give clearness the password patina is used to describe changes to the open layer of metallic element on a mint. This layer changes over the run of prison term as a result of interactions with environmental agents or contaminants. This interaction takes time and gives coins a unique appearance. In numismatics the news patina is frequently synonymous with the use of the words tarnish or tone .

Most collectors prefer to have coins with patina and it can take a great number of years to form this unique aesthetic and it can be removed in one miss judged consequence .
People have used diverse methods to attempt to restore or upgrade coins over the years and the majority of processes leave some very obvious distinguish distinguish signs .

How to tell if your coin has been tampered with :

clean coins often have a dulled but bright appearance that will look out of place in comparison to a well circulated mint .

You may see the appearance of greater than natural luster on the coin, specially if it is old .
Do not expect to see observation in old coins, they should appear dimmed and darkened .

The cartwheel shininess is not visible, coins that have not been tampered with should have a cartwheel of luster when you inspect them. This should be particularly apparent in uncirculated coins ! Expect to see radiating lines in a round practice. This should only be visible when the coin is turned.

Silver coins of old age will look grey but with black build up around the detail, this is an obvious sign of tampering. The patination can appear discrepant a well as the tone. Watch out for old brassy blank silver wear coins as these are most decidedly tampered with. Remember metals tarnish so look out for such examples and compare !

If the coin has a flat shininess but even is dated it has credibly been dipped, most coins will have a crisp, smooth or glistening luster if they are untouched and you can easily see the deviation .

Wizzed or tooled coins can be detected by minor abrasive marks on the surface of the coins, frequently the finish will be mirrored. Marks may appear across the stallion surface or equitable in a specific area. Often enlargement is needed in order to detect such marks and it is highly recommend that you invest in a adequate x10 microscope .

Tampered copper coins of senesce will appear to have a pale orange imbue not the classic orange or loss which they are known for. They may besides have a farinaceous timbre and can be spotted when compared to an original .

sometimes you will find old clean coins, these will have been cleaned in the past and left to acquire a ra tone whilst in storehouse. These coins will often appear to have a glazed luster under the tone and may catch you as having an odd combination of qualities .

The more you explore the world of coins the more accustomed you will become to such signs and traits .
It can be unmanageable to pick up such signs when buying coins on-line and ebay is ill-famed for broken quality images and doubtful sellers. Remember always do your inquiry when confronted by a new prospective seller. Look at reviews and ask for high quality images if you are not satisfied .
It is constantly thoroughly to have mention coins for comparison and if you feel the wish you may conduct small tests at home to examine the effects that coin cleaning can cause .
If you do wish to find out for yourself first hired hand the effects of mint cleanse if you are new to numismatics, I would advise using advanced broken value coins and a microscope to see the effects that these techniques cause. once you have an eye for the different tamper practices it should ensure greater success at telling the unchained from the tampered .

now I would like to point out that you can have an exception to the rule .
There are merely three instances that I would always justify when it comes to coin houseclean and these are as follows :

1
If you have PVC damage on a coin from storehouse, whoa befall ! This is evitable habit not PVC repositing devices !
This requires the use of acetone, be careful use gloves and a cotton bud. see you are in a well ventilated space and do not use nail polish remover buy acetone !

2
The mint has dirt or has built up debris on the surface. If this is the character I recommend holding it under cool distill water for a brief period of time no long than a few seconds and patting it dry with a indulgent fabric .

3
You have an ancient mint that needs to be identified. Leave the mint in a beaker of distill water for a number of days no longer than a week, then proceed to soak in olive oil for up to a calendar month. This should remove unwanted remainder and any build up without having to result to abrasive or damaging clean techniques.

I hope this information helps if you are new to collecting !
Remember it ‘s all about having that center for detail, finding reputable suppliers and taking your time ! Ask for gamey quality images if buying on-line and make certain if you are buying graded coins the third gear party is recognised and legitimate. No camera tricks ! Look for a good supplier and recognise the very from the bogus .
