Buying Coins: You Pay for the Metal or You Pay for the Whim
One silver ounce. Mexico, 1993. Veracruz Pre-Columbian Series. Uncirculated. The person who bought it already had one just like it at home and bought another. That gesture —repeating a purchase— explains the numismatic market better than any investment manual. Because two prices coexist in the same piece, and they have nothing to do with each other: the price of the metal it’s made of and the desire of the person pursuing it.
The purchase records for this hobby jump from a 1993 Mexican coin to a 1847 Cambodian tical, from Egyptian piastres of the British protectorate to gold escudos minted in Santiago, Chile. All share the same underlying question: how much of what you pay is silver and how much is history?
Silver Weight Isn't the Coin's Price
A common piece is usually worth what it weighs. The metal dictates the price, and if silver goes up, it pulls the coin with it. But as soon as a rare piece appears, the logic changes. An 8 Escudos from 1805 by Charles IV, 875 fine gold, 26.90 grams, and a mintage of only 44,000 examples, is one of the pieces that appear in the thread.
It's called learning, summarizes one of the veterans, who warns: coins piled up in a box, without order or conservation, rarely exceed their silver weight and little more. And there lies the boundary between collecting and accumulating. The piece-by-piece breakdown —weights, diameters, fineness, and official mintages— appears in several fact sheets in the thread.
Weigh and Measure Before Saying Thanks
In one case described on the forum, fraud slipped in through a second-hand platform. A coin of Belarus 20 rubles from 2006 arrived weighing 27.35 grams and measuring 40.11 millimeters, compared to the official 28.28 grams and 38.61 mm. A Russian 3 rubles from 2012, with a certificate of authenticity included, appeared weighing 29.32 grams when it should have weighed 33.94. The paper guarantees nothing.
The buyer weighed and measured the pieces immediately upon receiving them and contacted the seller.
Why Are Flea Markets More Expensive Than eBay?
A forum user recounts that a stroll through the numismatic flea market in Madrid's Plaza Mayor leads to a bitter conclusion: prices don't reflect the real world. The 2014 Koala was offered at 28 and 30 euros; the Karlillos, at 18 and 20; loose capsules, at 50 cents.
On eBay, with patience, much of that appears cheaper. The paradox is that those who complain about not selling anything are the same ones who don't compete with the whole world, but with the next stall.
Gold as a Safe Haven: 6 Grams is Better Than an Ounce
When the goal isn't to show off but to protect oneself, the recommendation is repeated: discreet pieces. 20 Francs, Sovereigns, Alfonsinos: coins weighing 6 to 8 grams, easy to move and store. For a large denomination, the Krugerrand. Some go further and buy genuine miniatures, like a 2003 gold piece from Samoa weighing only 1.24 grams.
The logic expressed here isn't about appreciation, but about having something tangible. One forum user also links a news story according to which George Soros exited gold to strengthen his position in banking.
Official Currency and Patriotic Narrative
Public issues play in another league. The National Coin and Stamp Factory celebrates anniversaries, and the buyer pays a premium for the narrative: the 30 euro coin for the 50th birthday of Felipe VI, weighing 18 grams and measuring 33 millimeters with a colored coat of arms, is the most recent example.
At the opposite extreme, the 100 euro coin from the Numismatic Jewels series, a 1609 centén weighing 168.88 grams, measuring 73 millimeters, and gold-plated, appears in the thread with its official data. And in memory remains the duro del error, the five pesetas from 1980 minted for the 1982 World Cup.
The Price That Doesn't Appear in Any Catalog
There's also collecting that isn't guided solely by metal. An ounce from Ghana's Lunar Skulls series, signed by its author and limited to 500 copies, is one of the pieces presented in the thread.
What seemed crazy at 500 or 600 euros for a Gulo gulo from Mongolia back then, today, according to a forum user, commands 1,200 euros.
