OBVERSE.--_Type._ Twenty-shilling and Ten-shilling-piece, king on horseback with or without artillery, armour, arms, etc., under horse’s feet. Crowns and Half-crowns, king in armour on horseback, but with very many variations in detail. One description is as much as our limits will allow. The Oxford Crown, the rarest in the series, has the king on horseback, in armour, to the left, crowned, double-arched crown, drawn sword in his right hand, a sash round his neck, coming under his left arm, the ends flying behind; the horse not caparisoned, having only a saddle cloth. On the field of the coin, beneath the horse, is a view of the city of Oxford, with the word OXON above it. This coin is beautifully executed. Shilling, Half-shilling, Quarter-shilling, Groat, Half-groat, and Penny, sinister bust profile, in robes, crowned, hair long and flowing, beard long. Some Groats and Half-groats have a rose crowned as also have Pennies. Halfpenny, a rose, no legend, or a rose crowned between C. R. The variations in the coins, consequent on the number of mints set up--London, Exeter, Aberystwith, Oxford, Bristol, Chester, Worcester, Weymouth, York, and other places--is very great; the differences being more or less important both as to mint marks and other features. _Legend._ C. CAR. or CAROLVS. D. G. MAGNA BRITAN. FRAN. ET HIBER. REX, variously abbreviated. Oxford Crown, CAROLVS. D. G. MAG. BRIT. FRAN. ET. HIBER. REX. REVERSE.--_Type._ Generally the royal shield. The Oxford Crown and some other coins have no device, except an ornament to divide the legends; and the Prince of Wales’ feathers three times repeated, or single, above. On some, the shield (which is as James I.’s) is oval, and mantled, sometimes crowned; others have shields, the quarterings terminating in a cross moline, etc. The smaller coins have sometimes a rose crowned, sceptres, or sceptre and trident in saltire, etc., or the declaration EXVRGAT, etc., in lines across. One Half-groat has two Cs interlinked, crowned. _Legend._ Oxford Crown, EXVRGAT DEVS DISSIPENTVR INIMICI. In the field of the coin, in two parallel lines, is RELIG. PROT. LEG. ANG. LIBER. PARL., beneath which is 1644, OXON, and above v. for value. A branch of leaves and flowers between the words of the first. Others have CHRISTO AVSPICE REGNO. Others IVSTITIA THRONVM FIRMAT, or TVEATVR VNITA DEVS. The groat has RELIG., etc., within a scroll on the field, EXURGAT, etc. _Rarity._ For the most part common. The Oxford crown is of the most extreme rarity, and most of the Oxford mintages are rare, as are those of Aberystwith and other places.
