Got the set and, whilst it's by no means flawless, it isn't that bad either. The coins don't appear to be in Brilliant Uncirculated standard. In fact, the pack makes no mention that they're meant to be. It is termed "Currency Coin Collection", suggesting these are examples of the same coins struck for circulation.
If I look closely, I might see the odd trace of a finger mark here and there, and the coins have a few nicks in, but nothing bad enough to send back and demand a refund. Eurocoin's posts have probably helped though in that I was expecting the worst. If he'd said they're flawless and perfect, I'd have been disappointed with any very slight defect. That's often the case with me though - build something up and I'll almost certainly be unhappy. Talk it down and I'm usually satisfied with it.
