cabinet friction: Slight surface wear on a coin, token or medal caused by friction between it and the tray or envelope in which it is contained.
friction - The rubbing of a coin against another coin or hard object that results in wear on its surface. Typically, friction causes unwanted wear on a coin resulting in lower desire and value of a coin.
friction: the rub or wear on a coin.
frost: on Uncirculated coins, a crystalline luster. On Proof coins, the slightly grainy finish that is given to the devices.
Friction - A disturbance which appears either on the high-points of a coin or in the fields, as a result of that coin rubbing against other objects.
roll friction Minor displacement of metal, mainly on the high points, seen on coins stored in rolls.
coin friction Term applied to the area resulting when coins rub together in rolls or bags and small amounts of metal are displaced. See also roll friction.
coin show A bourse composed of coin dealers displaying their wares for sale and trade.
album friction or slide markings - see friction.
alloy - a mixture of two or more metals melted into one compound.
Album Friction
Similar to album slide marks, though the friction may be only slight rubbing on the high points. See Also: Slide Marks, Album Slide Lines.
Album friction - A less severe instance of album slide marks. Album friction shows as slight rubbing on the high points.
Cabinet Friction - Sometimes a coin that looks in nearly mint condition but has a slight rub on it will be termed as suffering from 'Cabinet Friction'.
Cabinet Friction
Minor wear on the high points of an otherwise uncirculated numismatic piece which has been stored in a tray or cabinet. The wear is caused by rubbing when the tray or cabinet is moved and will adversely affect its value.

Post confederation Canadian numismatics.
Cabinet Friction - If coins are kept and displayed in wooden cabinets they tend to move about when the tray is taken out and rubbing or friction often occurs on the high points.
Friction - Any wear or rubbing on the surfaces of a coin.
Frosted - A textured, almost crystalline, surface usually seen on the raised portions of a proof coin.
Cabinet Friction
Refers to friction or rubbing marks on the highest elements of a coin, as if it was dragged across a wooden cabinet drawer. Wooden storage cabinets were the most popular way to display coin collections up to about the 1930s.
Cabinet Friction - Sometimes called "cabinet wear" or "cabinet rub" is wear to the higher portions of a coin's design, caused by being kept in an unlined wooden cabinet drawer over a long period of time.
Rub Light friction, usually noticeable on an otherwise fully Uncirculated coin. A blazer that might fetch $10,000 drops to perhaps $1000 with rub.
(Those coins struck in late 1837 were dated 1838.) cabinet friction Slight disturbance seen on coins (usually on the obverse) that were stored in wooden cabinets used by early collectors to house their specimens.
abrasions - Light rubbing or scuffing from friction, not to be confused with hairlines or bag marks.
adjustment marks - Small striations or file marks found on early United States coins.
Modern coin collectors Grade coins according to the amount of Wear or detail removed from handling and friction in purse and pocket. Our illustration shows five coins showing differing amounts of wear.
Friction first shows on the top ridges of the star on the obverse and on the Roman numeral on the reverse.
Die Wear - After striking coins repeatedly, due to heat and friction, the surfaces of the dies show wear. Periodically, the striking process is halted and one or more of the dies are resurfaced to remove blemishes.
When grading Coronet quarter eagles, friction begins to first show on the tip of the coronet and above the eye on the obverse, and on the wing tips and claws of the eagle on the reverse.
A coin having any wear, even the slightest friction, cannot be uncirculated, period. I have always been puzzled because slight wear counts for so much and heavy marks, even cuts, called bagmarks, are found to be acceptable on uncirculated coins.
Terms such as Proof-50 and Proof-55 describe coins originally struck with Proof finish but which later were subjected to friction or even circulation.
pressing the tip of the bent thumb of the same hand against the palm-side of the index finger, so that friction there holds the thumb back from extending further, ...
Uncirculated; just the barest touch of cabinet friction, with frosty mint lustre. Perfectly centered, and what is most important, an unusually bold impression. Undoubtedly one of the earliest impressions of the die.
Like all mechanical machines, a lubricant is needed in the coin press to prevent the metal parts from causing friction to each other.
It is important to note, however, that many mint state coins will have slight "friction" on the high points or in the fields, resulting from coins rubbing against-each other in rolls or bags.
Extremely Fine: As a coin circulates friction begins to show as a slight loss of detail on the hair braid of the Indian and upper front leg of the Buffalo.
Friction: Low
Essentially polypropylene album pages are crystal clear, the plastic is quite 'slippery' to touch, and the material shows good 'stretching' before it will tear. A key thing to note is that polypropylene pages are odourless.
There may, however, be friction on areas such as the bridge of Liberty's nose and the brow. As stated above, it is not uncommon for an MS-60 coin to show less eye appeal than one graded AU-58.
Wear is not apparent to the naked eye, though slight rubbing or cabinet friction may be present under magnification. A coin may feature some flatness of strike, which may be common for that date and type.
Uncirculated - Without rub, friction or wear from circulation.
Variety - A minor change from the basic design type of a coin.
Year Set - Collection including one coin from each year within a series.
In order to remove a coin from the album, you had to slide the plastic cover across the face of the item. The friction of the plastic against the coin's DEVICES sometimes caused un-removable lines to appear. See Also: album friction ...

Even slight friction will result in some ink corning off on your fingers. The thin layer of ink that wasn't absorbed by the paper will soon be worn away during handling and counting at the bank or even minor circulation.
Luster: or the brilliance, cartwheel, sheen and contrast of the coin. Again, each issue's characteristics are considered. Evidence of cleaning, retoning or friction is also examined.
The "dry" nature of the coin and the high friction caused by pressing soon removes any surface cheese from the dies and leaves a metal-to-metal contact.
