TICKEY COIN VALUE SOFTWARE
Machines such as vending machines are programmed with software and sensors to recognise these circulation coins and to accept them accordingly. Various ridges, rims, serrations and different metals on the coins are incorporated as part of the security features. These coins are used in everyday transactions, circulating alongside banknotes. Circulation coins are made of metal or alloy.An important consideration in having the different sizes and rim finishes was that visually impaired people could identify the particular denomination with their fingers when transacting. The 10c is the smallest at 16mm and the R5 is the largest at 26mm. South Africa has six coin denominations in circulation, namely, the 10c, 20c, 50c, R1, R2 and the R5.In 2019 Pratley Putty, the world’s first epoxy adhesive invented by South African engineer George Pratley and used by NASA aboard its Ranger moon-landing craft over 50 years ago.
TICKEY COIN VALUE SERIES
The ‘South African Inventions’ theme was introduced on the Crown and Tickey coin series in 2016 to highlight globally relevant inventions and firsts by South Africans. Only 1 000 of the sterling-silver R2 crown coins and 1 000 of the sterling-silver 2½ c tickey coins have been minted.Ī combination set, comprising the two coins and a sterling-silver miniature sculpture of the eye, packaged in a beautiful piano-finish varnish walnut-wood box, is also available.
In a way, therefore, this year lends itself perfectly well to commemorating our history, celebrating our successes, and recognising our inventions and inventors,” she adds. “In ophthalmology, the average vision is 20/20 vision. “The influence of the invention is evident in the number of cataract surgeries performed globally, which the American Optometric Association estimates at 26-million every year,” notes Mamabolo. The ingenious design on these coins allows for a surprise: when the smaller tickey is placed on the bigger crown, it gives the impression of a retinal cryoprobe procedure. The retinal cryoprobe has played a key role in improving the quality of life of many around the world.”
“Innovation and disruption are two sides of the same coin. SA Mint MD Honey Mamabolo says the ongoing crown and tickey series pays homage to local ingenuity and celebrates the pioneering efforts of South Africans. Extraordinary invention, ingenious design In South Africa, it has been identified as a national health priority, as it remains the leading cause of blindness in the country, according to the South African Optometric Association. The “posterior capsular opacification”, or cataract is the world’s leading cause of blindness, accounting for about 42% of all cases. If left untreated, cataracts may eventually cause blindness. The cataract – or other unwanted tissue – can then be removed, with no risk of destroying healthy adjacent tissue. The cryoprobe is a large, pen-like instrument used in cryosurgery, a technique commonly used to treat cataracts.ĭuring cryosurgery, the cryoprobe is inserted into a cut in the eye to deliver extremely cold liquid gas with precision to freeze onto a cataract. The retinal cryoprobe was commercialised by Amoils in 1965 while he worked at the Baragwanath Hospital in Soweto. Which is your favourite SA Mint South African invention range?
