- See Lustre.
SCARCE
- See Common, Rare, Scarcer than common but not as difficult as rare.
SCRATCH

SEMI REGAL ISSUE
- Coinage produced with the authority of a local government, eg. as with Nova Scotia Semi Regal Tokens during 1823-43, but without the knowledge and authority of the home British Government. Those coins having the backing of the home government are called Regal issues.
SELLER'S FEE
- A fee charged the seller of a coin at an auction. usually 10% of the sale price but can be lower depending on the volume of coins consigned by the seller for that auction. See also Buyer's Fee.

SET PREMIUM
- A price premium charged for a complete set of coins, usually only on those sets of the finest quality usually available or sets that are likely without competition in terms of overall quality.

SET-UP
- See Adjustment.
SET-UP TRIALS
- See Adjustment.
SHELDON GRADING SYSTEM
- A grading scheme introduced by Dr. William Sheldon in the late 1940's and was based on a numerical rather than adjectival scale with gradation from 1 to 70. Originally developed for US Copper but has since been adopted for all other coinage of Canada and the US by both the CNA and ANA. The uncirculated range is from Basic Uncirculated MS-60 (MS - Mint State) to Perfect Uncirculated MS-70. Sometimes incorrectly referred to as the Mint State System.
SHIMMERING

SLIME
- See Green Slime.
SLUG
- A term applied to the $50, gold coin issued by various private mints in California from 1851 to 1855 occurring in both round and octagonal shapes. Also tokens manufactured expressly for use in certain coin-operated machines. Also a blank occasionally mistaken for a coin planchet.

SOUVENIR COIN
- A token of a commemorative or promotional character which may purport to have some limited exchange value.

SPECIALIST
- One who specializes in a particular coin series and develops knowledge usually unknown to a generalist and usually not in print for the public to access easily. See Knowledgeable.
SPECIE
- Money in the form of coin.
SPECIMEN
- A coin prepared with special care as an example of a given issue. The highest quality specimens are Proofs but until 1973 the Royal Canadian Mint did not have the capability to do this. Canadian specimens have been matte (and semi-matte) with a granular, dull or monotone surface and also brilliant with mirror fields and a frosted raised portion. Also a synonym for a numismatic item, eg. a very rare specimen meaning example.
SPLIT GRADE
- See Intermediate Grade.
SPURIOUS
- A false piece made to deceive, often an original creation rather than a copy of a known item. Not genuine. Counterfeit. False.
SQUARE RIM
- A requirement of a Proof coin. The square flat or "wire" rim is a result of the intense pressure used in striking proof coins. The pressure forced the metal to flow out to the rims, to the limiting confines of the collar die. This was a thick cylinder which prevented the planchet from expanding too far outward during the striking of the coin. The rims thus have a more finished, square look, as opposed to the more rounded rims of a business strike. Occasionally a tiny amount of the metal squeezed past the collar die and appears as a very thing upraised "wire" edge on the rim of the coin. Also Wire Edge.
STANDARD COIN
- A coin originally issued with an intrinsic value equal to its face value or which was to pass for its intrinsic value.
STEAL
- See Underpriced.
STRIATIONS
- A series of parallel and thin lines. See Die Polishing Lines, and Planchet Striations.
STRIKE
- To stamp the coin design onto a blank. Also one of the grading criteria of a coin and may vary from a full strike in which all of the intended design detail of the engraver shows to a very soft or weak strike where one or more areas of the coin display less than full detail.
SULPHUR
- A chemical that reacts with various metals, especially silver and copper and results in a coating forming over the surface of the metal giving it a coloured appearance.
SULPHURATED HOLDER
- A coin holder (usually envelope) containing sulphur traces. coins stored in them will have a tendency to tone over time because of the sulphur presence. Higher temperatures and humidity levels will speed up the amount of the toning that appears in a given time.
SUPERB
- Reference to a coin, token, or medal that is truly an exceptional uncirculated example. Usually displays a superior than typical lustre, surface condition and strike to normally seen uncirculated examples. Commonly graded as MS-67 on the numerical scale.
SURFACE RESIDUE
-A milky white coating left on the surface of a coin after an attempt has been made to remove heavy dark tarnish or also improperly rinsing a coin in hot water after being treated with "dip" etc.
SWEATING COINS
- This was a way of obtaining flecks of gold from gold coins without their being obviously reduced in metallic content. The gold coins were placed in a small container and then shaken together so that they would scrape each other. this removed flecks of the gold without being so obvious as the clipping technique (see Clipping). Given enough coins, the method could yield several dollars in gold beyond the face value of the coins being worn in this way.
