coins
aardvarchaeology | September 3, 2014Here's a neat case of self-perpetuating archaeology. Medieval history spawned sword & sorcery literature. This literature spawned tabletop fantasy role-playing games and Medieval re-enactment groups. These games and groups spawned live action role playing. And now the larpers have created a market for faux-Medieval coinage, which they are buying at game stores, using at larps and dropping here and there. Metal detectorists are starting to find coins like the one in the picture and submitting them to intrigued museum curators.
Can anybody tell me the name of the company that makes/made…
aardvarchaeology | July 21, 2014Deep in a single square metre of trench D at Landsjö castle, on the inner edge of the dry moat, we found five identical coins. Boy are they ugly. They're thin, brittle, made of a heavily debased silver alloy and struck only from one side; they bear no legend and the image at the centre is incomprehensible. But I love them anyway, because they offer a tight date: this coin type was struck for King Valdemar Birgersson c. 1250-75. And the first written mention of Landsjö dates from 1280, so it all works out.
Valdemar became king because he had an extremely powerful and ruthless father, the jarl…
aardvarchaeology | July 14, 2014A fun thing about historical archaeology, the archaeological study of areas and periods with abundant indigenous written documentation, is when the archaeology challenges the written record.
According to the patchily preserved historical sources, Landsjö hamlet was a seat of the high nobility in about 1280 but then became tenant farms no later than 1340. This means that the castle on Landsjö islet was probably in good defensible shape and inhabited in 1280 but not after 1340.
During last week's excavations we found a previously unknown strong wall delimiting the castle's high inner bailey,…

This is an interesting video showing how the â¬2 coin is made. This coin consists of two different metals that are squeezed together into one coin. Interestingly, it uses recycled copper -- I wonder how many construction sites have lost their copper piping to thieves who then sold it to recyclers for manufacture into Euros? I also have embedded a second video that discusses the history of coin making as well as describing how less complex coins are made.
Another look at coinmaking (admittedly, not as fancy as…
