S-type load cells; used in tension applications where you will find static and dynamic loads. Compression load cells; used in truck scales, large platform scales, weighbridges and hopper scales. Ring Torsion load cells; used in high accuracy hoppers, silos, platforms and pallet scales.
A coin catalog (or coin catalogue) is a listing of coin types. Information may include pictures of the obverse and reverse (front and back), date and place of minting, distribution type, translation of inscriptions, description of images, theme, metal type, mintage, edge description, orientation of the coin, weight, diameter, thickness, design credentials, shape and prices for various grades.
In coin collecting, the condition of a coin (its grade) is key to its value; a high-quality example with minimal wear is often worth many times more than a poor example. Collectors have created systems to describe the overall condition of coins. Any damage, such as wear or cleaning, can substantially decrease a coin's value.
Button, coin, or watch cells. A button cell, watch battery, or coin battery is a small battery made of a single electrochemical cell and shaped as a squat cylinder typically 5 to 25 mm (0.197 to 0.984 in) in diameter and 1 to 6 mm (0.039 to 0.236 in) high – resembling a button.

Several sizes of button and coin cells, some of which are silver oxide. A silver oxide battery (IEC code: S) is a primary cell using silver oxide as the cathode material and zinc for the anode. These cells maintain a nearly constant nominal voltage during discharge until fully depleted. [2]
Coin grading [1] is the process of determining the grade or condition of a coin, one of the key factors in determining its collectible value. A coin's grade is generally determined by six criteria: strike, preservation, luster, color, attractiveness, and occasionally the country/state in which it was minted. Several grading systems have been ...
