First attempt at putting a SCP together, what do you think?
Needs definite tone work, this is most noticeable in the test logs, I believe one mentioned a subject 'passing out'? no scientific report would include a phrase like that, use unconscious or another synonym of unconscious. There are a couple more issues like that throughout the article and it feels like a layman wrote up the article (from a Foundation viewpoint), you have to remember that this, as I said previously, is a scientific report so use the big words.
I like the concept behind this but I feel the back story could be improved, perhaps make the coins a factory or Wondertainment product (not only will this be easier to convey but it will give the article access to more of the coins). So I would look into those options, the factory tends to produce anomalous and 'spooky' items while Wondertainment produces more 'fun' and child-centric items that have anomalous properties and can be horrific if used wrong.
Just my 2 cents on it, it's a while away from being full article worthy but I honestly like this idea and I think it could do pretty well.
