What WERE their findings though? I read that link and 80% of it was talking about the "history of Venezuela’s elections"
Only relevant bit was 5 people went to a few poling stations each and they didn't see anything odd and people seemed to be happy to vote. I didn't see them claim to have done anything that could be considered proving the elections were fair one way or another, other than no obvious fraud at the polling stations themselves.
Either that article or maybe another one I read says the coins are being traded at ten times their face value by collectors so yeah, maths seems right.
Like of lot of this kids stuff it's popular, look at how much to those bloody "free" Woolworths(?) little plastic groceries they give away from time to time go for!
