Six passes that take an hour, what to pull out immediately and the mistakes that destroy value in the first ten minutes. https://collectioner.art/en/journal/inverted-jenny-and-stamp-errors https://collectioner.art/en/journal/inverted-jenny-and-stamp-errors Wed, 09 Sep 2026 09:00:00 GMT Why two-colour printing produced the famous American inverts, what separates an error from a plate flaw, and how the classic fakes are made – reperforating, regumming and photographic copies. https://collectioner.art/en/journal/trading-duplicates https://collectioner.art/en/journal/trading-duplicates Wed, 09 Sep 2026 09:00:00 GMT Duplicates are the currency of collecting.

What actually separates a keeper from pocket change: the date and mint mark under the date, a handful of key issues, the 1943 steel cent and why cleaning removes value. https://collectioner.art/en/journal/buying-from-photographs https://collectioner.art/en/journal/buying-from-photographs Tue, 08 Sep 2026 09:00:00 GMT Almost everything is now bought from a picture, and most disputes come from what the picture left out. The shots a listing must include for stamps, coins and paper, the warning signs in an image and what to ask before paying. https://collectioner.art/en/journal/cinderella-labels https://collectioner.art/en/journal/cinderella-labels Tue, 08 Sep 2026 09:00:00 GMT Charity seals, poster labels, revenue stamps, local fantasies and matchbox labels all look like postage and none of it is.

Thickness, surface, colour and fluorescence on one side; original, disturbed, regummed or absent on the other – and how to check each without damage. https://collectioner.art/en/journal/repair-and-restoration https://collectioner.art/en/journal/repair-and-restoration Tue, 08 Sep 2026 09:00:00 GMT Stabilising an item is conservation; changing how it looks is restoration; hiding damage is a defect. Where the line runs across paper and metal, what an amateur may safely do and why every intervention must be recorded. https://collectioner.art/en/journal/stamp-shades-and-colour https://collectioner.art/en/journal/stamp-shades-and-colour Tue, 08 Sep 2026 09:00:00 GMT Colour differences come from three sources: separate printings, chemical change and light damage. Only the first is a catalogue variety. How to tell them apart, why comparison beats memory and how to photograph colour honestly. https://collectioner.art/en/journal/definitives-and-commemoratives https://collectioner.art/en/journal/definitives-and-commemoratives Mon, 07 Sep 2026 09:00:00 GMT Definitives are the everyday workhorses, reprinted for years; commemoratives are short one-off issues. The difference decides how they were used, how they survived and why the plain-looking one is often the harder to collect. https://collectioner.art/en/journal/how-enamel-badges-are-made https://collectioner.art/en/journal/how-enamel-badges-are-made Mon, 07 Sep 2026 09:00:00 GMT Hot enamel is glass fused into a struck recess; cold enamel is paint under lacquer. Knowing which you are holding explains the price difference, the way the badge ages and how copies give themselves away. https://collectioner.art/en/journal/coin-mint-marks https://collectioner.art/en/journal/coin-mint-marks Mon, 07 Sep 2026 09:00:00 GMT A mint mark is a tiny letter or symbol saying which mint made the coin – and it often separates a common coin from a scarce one. Where to look, what Soviet coins carry, and why the same year can mean two different coins. https://collectioner.art/en/journal/stamp-overprints https://collectioner.art/en/journal/stamp-overprints Mon, 07 Sep 2026 09:00:00 GMT An overprint is printing added to a finished stamp – to change its value, its country or its purpose. Why postal services did it, the five kinds you will meet, why overprints are forged more than anything else and how to check one. https://collectioner.art/en/journal/proof-and-circulation-strikes https://collectioner.art/en/journal/proof-and-circulation-strikes Mon, 07 Sep 2026 09:00:00 GMT The same design exists as an everyday coin and as a collector striking with mirror fields and frosted relief.

What the formats are, how to recognise them and why breaking one up destroys it. https://collectioner.art/en/journal/coin-edges https://collectioner.art/en/journal/coin-edges Mon, 07 Sep 2026 09:00:00 GMT The edge started as an anti-fraud device against clipping and stayed as an identifying feature. Five edge types, what an edge inscription records, and why the edge is the first place to check on a suspicious coin. https://collectioner.art/en/journal/which-country-is-this-stamp https://collectioner.art/en/journal/which-country-is-this-stamp Mon, 07 Sep 2026 09:00:00 GMT Half of the world's stamps do not say their country in an alphabet you read. Six ways to find it anyway: the currency, the script, the portrait, the emblem, the postal union inscription and the country that no longer exists. https://collectioner.art/en/journal/arranging-an-album https://collectioner.art/en/journal/arranging-an-album Sun, 06 Sep 2026 09:00:00 GMT An album is an argument, not a container.

What holds attention instead: a theme they chose, objects they may touch, a finishable goal and a story attached to each piece – plus the rules that keep both child and collection safe. https://collectioner.art/en/journal/stamp-perforation https://collectioner.art/en/journal/stamp-perforation Sun, 06 Sep 2026 09:00:00 GMT Perforation is counted over a fixed length of two centimetres, not guessed.

Why natural toning is desirable, how cabinet toning differs, the signs of artificial toning and why removing any of it costs more than it gains. https://collectioner.art/en/journal/what-makes-a-stamp-rare https://collectioner.art/en/journal/what-makes-a-stamp-rare Sun, 06 Sep 2026 09:00:00 GMT Rarity is about how many survive in a given state, not about age or how pretty the design is. Six things that create it – print run, survival rate, state, variety, use and provenance – and the four assumptions that mislead beginners. https://collectioner.art/en/journal/why-coins-turn-green https://collectioner.art/en/journal/why-coins-turn-green Sun, 06 Sep 2026 09:00:00 GMT Green on a coin is copper reacting with moisture and air. Stable green is patina and stays put; powdery bright green spreads and eats the metal. How to tell them apart, why cleaning is the wrong answer to both and how to stop the active kind. https://collectioner.art/en/journal/banknote-condition https://collectioner.art/en/journal/banknote-condition Sat, 05 Sep 2026 09:00:00 GMT Paper money is graded by folds, not by brightness.

What makes one collectible, why most modern covers are common, and the five things that separate an interesting cover from a decorative one. https://collectioner.art/en/journal/stamp-hinges-and-mounts https://collectioner.art/en/journal/stamp-hinges-and-mounts Sat, 05 Sep 2026 09:00:00 GMT A hinge is a small folded paper tab glued to the back of a stamp, and on unused stamps it leaves a permanent mark.
