Palladium isn’t magnetic. It’s paramagnetic. It has a weak magnetic attraction ensuring pure-palladium items remain immune to magnets of any size and strength. Palladium is paramagnetic due to the presence of unpaired electrons in its electronic structure, specifically in the 4d orbitals. Palladium alloyed with magnetic and ferromagnetic metals exhibits magnetic properties. Why is Palladium … Read more

A coin field is the flat, blank surface area surrounding a coin’s main design, distinct from raised reliefs and inscriptions. It contrasts with the design to enhance visual impact, and is different from both the obverse (front) and reverse (back) sides. Coin field refers specifically to the background area on either side. Coin fields are … Read more

Silver isn’t magnetic. It’s diamagnetic. Pure silver doesn’t magnetize because of its electronic configuration. Silver atoms have paired electrons with no unpaired electrons, meaning there’s no magnetic dipole moment required for magnetism. Real sterling silver (925 silver), 999 silver, 958 silver, 900 silver, 800 silver, and other silver alloys are all diamagnetic because they contain … Read more

Fool’s gold is a naturally occurring mineral that resembles real gold but has minimal value. Fool’s gold is scientifically known as pyrite (chemical name is iron sulfide, FeS₂). Other names for fool’s gold are brass, brazzle, and brazil, primarily used to refer to pyrite found in coal. While real gold costs over $100 per gram, … Read more

The most valuable and rarest US coins ever sold span over a century of American minting history. Topping the list is the 1933 Saint-Gaudens Double Eagle, which sold for $18.9 million, followed by the 1849 Coronet Head $20 Double Eagle, the 1794 Flowing Hair Silver Dollar (among the earliest US silver dollars), and the 1787 … Read more

A coin’s edge is the border encircling its circumference, sometimes called “the third side,” and serves both decorative and security purposes. Common types include smooth (plain), reeded (grooved), lettered, decorated, and knurled edges. Reeded edges are the most effective at preventing counterfeiting and coin clipping. This is why U.S. dimes and quarters feature reeding. Coin … Read more

White gold patina is a natural change in appearance that happens as the rhodium plating on white gold jewelry wears away, revealing the warmer, yellowish tone of the underlying gold alloy. This differs from tarnish, which is undesirable oxidation. White gold patination is simply the plating fading, and some people like the look while others … Read more

Rose gold vermeil is jewelry made by coating a sterling silver base with a thick layer of rose gold, at least 10k purity and 2.5 microns thick, giving it the look of solid rose gold at a more affordable price. It differs from regular rose gold plating, which lacks standardized thickness or purity and can … Read more

Red gold is a real gold alloy created by combining yellow gold with copper and trace amounts of silver. The high copper content (higher than rose gold) gives red gold its distinctive pinkish-red hue and increases its hardness and durability. Red gold is available in 10k, 12k, 14k, and 18k variants, with 14k and 18k … Read more
