Handle and measure

Handling and measuring tools are essential accessories for any collector wishing to examine, identify and evaluate their coins, banknotes and other numismatic objects under the best possible conditions.

Coin tongs allow coins to be held without direct finger contact, thus avoiding the deposit of fats and skin acids that can alter surfaces and cause irreversible marks. They come in several materials, including stainless steel, plastic and bamboo, with straight or angled tips depending on requirements.

Gauges and callipers allow the diameter and thickness of a coin to be measured precisely in millimetres. This data is essential for identifying a coin, verifying its authenticity or classifying it in a suitable holder or storage solution. Digital models offer direct reading and precision to one tenth of a millimetre.

Numismatic precision scales measure the exact weight of a coin in grams with a precision of one hundredth or one thousandth of a gram. Weight is one of the fundamental criteria for identifying and authenticating a coin, as each official issue must meet strict weight standards defined by the issuing authorities.

Handling rods and spatulas complement these tools by offering suitable solutions for handling delicate coins, medals or banknotes without risk of deterioration.

Sizing gauges and specialised graduated rulers facilitate the rapid sorting and classification of large collections, allowing coins to be grouped by diameter without systematically resorting to an electronic measuring instrument.

All of these instruments meet the requirements of preventive conservation and numismatic expertise, in line with the professional practices of museums, auction houses and specialist dealers.
