"Trial of the Pyx The Trial of the Pyx () is the procedure in the United Kingdom for ensuring that newly minted coins conform to the required standards. These trials have been held from the twelfth century to the present day, normally once per calendar year. The form of the ceremony has been essentially the same since 1282 AD. These events are trials in the full judicial sense, presided over by a judge with an expert jury of metallurgical assayers. Given modern production methods, it is unlikely that coins would not conform, but this has been a problem in the"

These standards resulted in a high rejection rate for newly-coined sovereigns, though less than for the half sovereign, which sometimes exceeded 50 per cent. When the Royal Mint was rebuilt in 1882, a deciding factor in the decision to shut down production for renovation rather than transition to a new mint elsewhere was the Bank of England's report that there was an abnormally large stock of sovereigns, and"

"Proof coinage Proof coinage means special early samples of a coin issue, historically made for checking the dies and for archival purposes, but nowadays often struck in greater numbers specially for coin collectors (numismatists). Nearly all countries have issued proof coinage. Preparation of a proof striking usually involved polishing of the dies. They can usually be distinguished from normal circulation coins by their sharper rims and design, as well as much smoother ""fields"" – the blank areas not part of the coin's design. The dies for making modern proof coins are often treated with chemicals to make certain parts of"

Each year on the last Monday in July, under the inspection of the Chief Justice, the Secretary and Comptroller of the Treasury, the Secretary of State, and the Attorney General, the coins were to be assayed and if the coins did not meet established standards, the officers were disqualified from office.

During 1561 a number of gold half-pounds and crowns were also minted, though it is not clear whether these were pattern coins or coins minted for circulation, but it has been suggested these coins were minted in conjunction with the queen's visit to the mint.

This debasement was recognised as a mistake, and during Elizabeth's reign newly minted coins, including the testoon (now known as the shilling), had a much higher silver content and regained their pre-debasement value. Shillings were minted during the reign of every British monarch following Edward VI, as well as during the Commonwealth, with a vast number of variations and alterations appearing over the years.

After relocating to its new home on Tower Hill, the Mint came under increased scrutiny of how it dealt with unrefined gold that had entered the country. Initially the Master of the Mint was responsible for overseeing the practise since the position's inception in the 1300s, however the refinery process proved too costly and suffered from a lack of accountability from the master.

According to a description of the 1948 meeting, silver coins selected for assay were first placed between steel rollers until the thickness was reduced to , and then were chopped into fine pieces and dissolved in nitric acid. The fineness of the silver in the coin could be determined by the amount of salt solution needed to precipitate all the silver in the liquid.

These flat rolls or sheets of metal are then punched out into round blanks that are a little larger than the coin being struck. The blanks are then subjected to an annealing process that softens the metal through heating to approximately 750 degrees Celsius (1400 degrees Fahrenheit) and are then slowly air cooled. They are then washed to remove residue from the annealing process and dried. The blanks then go through an upsetting mill that raises the rim on the edge of the coin. Finally, the"

Newton's chemical and mathematical knowledge proved of great use in carrying out this Great Recoinage of 1696, a process that was completed in about two years. Newton was subsequently given the post of Master of the Mint in 1699, a post worth between £1,200 and £1,500 per annum. Despite counterfeiting being considered high treason, punishable by hanging, drawing and quartering, convicting even the most flagrant criminals could be extremely difficult. Undaunted, Newton conducted more than 100 cross-examinations of witnesses, informers,"

The Counting Committee verified that the number of each type of coin in packets selected from the pyx matched what Mint records said should be there. The Weighing Committee measured the weight of coins from the pyx, checking them against the weight required by law. The Assaying Committee worked with the Philadelphia Mint's assayer as he measured the precious metal content of some of the coins. In some years there was a Committee on Resolutions—in 1912, it"

The prospect of machine-struck coinage caused uproar amongst the moneyers already employed by the mint, and led to a public battle of pamphlets in which Blondeau set forth the advantages of his machinery and techniques, and those at the Mint denigrated them. The officers of the Mint threatened Blondeau with an indictment of high treason, and accused him of libel and counterfeiting.

A 1697 Act of Parliament tried to stem this tide by raising the minimum acceptable fineness on wrought plate from sterling's 92.5% to a new Britannia silver standard of 95.83%.
