An abacus, also called a counting frame, is a hand-operated calculating tool which was used from ancient times in the ancient Near East, Europe, China, and Russia, until the adoption of the Arabic numeral system. An abacus consists of a two-dimensional array of slidable beads. In their earliest designs, the beads could be loose on a flat surface or sliding in grooves. Later the beads were made to slide on rods and built into a frame, allowing faster manipulation.
A coin is a small object, usually round and flat, used primarily as a medium of exchange or legal tender. They are standardized in weight, and produced in large quantities at a mint in order to facilitate trade. They are most often issued by a government. Coins often have images, numerals, or text on them. The faces of coins or medals are sometimes called the obverse and the reverse, referring to the front and back sides, respectively. The obverse of a coin is commonly called heads, because it often depicts the head of a prominent person, and the reverse is known as tails.
Numismatics is the study or collection of currency, including coins, tokens, paper money, medals and related objects.

Casino chips are small discs used as currency in casinos. Larger, rectangular gaming plaques may be used for high-stakes games. Poker chips are also widely used as play money in casual or tournament games, are of numismatic value to casino chip collectors, or may be kept as souvenirs.
Exonumia are numismatic items other than coins and paper money. This includes "Good For" tokens, badges, counterstamped coins, elongated coins, encased coins, souvenir medallions, tags, wooden nickels and other similar items.

In numismatics, token coins or trade tokens are coin-like objects used instead of coins. The field of token coins is part of exonumia and token coins are token money. Their denomination is shown or implied by size, color or shape. They are often made of cheaper metals like copper, pewter, aluminium, brass and tin, or non-metals like bakelite, leather and porcelain.
The Magdalen Island penny token was a token that was originally issued for use on that island and throughout Lower Canada and the Maritime Provinces in the early 19th century. This token was issued in 1815 by Sir Isaac Coffin, who was granted the island by the British government in reward for his loyalty to the crown during the American Revolutionary War. While not a rare coin, it is hard to find in anything but worn condition, and even prices for pieces in the lowest grades tend to start at about at about C$100 and go up rapidly from there.
The livre was the currency of Kingdom of France and its predecessor states of Francia and West Francia from 781 to 1794. Several different livres existed, some concurrently. The livre was the name of coins and of units of account.

Telephone tokens were token coins once widely used for making telephone calls from public telephones in place of ordinary coins. They were also sometimes used as a medium of exchange and as a collectible. Telephone tokens were once widely used in Europe, Israel, Japan, and South America, but have since been largely superseded by telephone cards and credit cards.
A piedfort is an unusually thick coin, often exactly twice the normal weight and thickness of other coins of the same diameter and pattern. Piedforts are not normally circulated, and are only struck for presentation purposes by mint officials, or for collectors, dignitaries and other VIPs. Piedfort is less commonly spelled "piefort".
The British pre-decimal penny was a denomination of sterling coinage worth 1⁄240 of one pound or 1⁄12 of one shilling. Its symbol was d, from the Roman denarius. It was a continuation of the earlier English penny, and in Scotland it had the same monetary value as one pre-1707 Scottish shilling. The penny was originally minted in silver, but from the late 18th century it was minted in copper, and then after 1860 in bronze.
The British twopence (2d) coin was a denomination of sterling coinage worth two pennies or 1/120 of a pound. It was a short-lived denomination in copper, being minted only in 1797 by Matthew Boulton's Soho Mint.
Bouquet sou were a series of tokens that were created for use primarily within Lower Canada in the mid- to late-1830s. Roughly equivalent in value to a half penny, the "bouquet sou" were so called because they displayed a group of heraldic flowers tied together with a ribbon on their obverse. The group of flowers were encircled by one of several legends, which might say "Trade & Agriculture / Lower Canada", "Agriculture & Commerce / Bas Canada" or some variant of these that might also substitute the name of the issuing bank. The other side most typically gave the denomination of "un sou", surrounded by a wreath and the words "Bank Token" and "Montreal". There are a large variety of these tokens, distinguished primarily by the number and variety of flowers that appear in the "bouquet", along with the differences in the legends that appeared on either side of the token. They were initially issued by the banks of Lower Canada, and were later imitated by speculators who produced tokens that looked similar, but were underweight for their denomination. These coins also circulated to Upper Canada, as at least one archeology dig attests. Large numbers of these tokens were produced and many examples can easily be obtained for only a few Canadian dollars, though a few rare varieties can command significantly higher prices.
