Spink prices are often high, especially compared to ebay, and unless the coin was £160 from a reputable dealer, who knows exactly what grade it is. £160 seems fair enough for UNC, perhaps high for EF. So if it's in the middle you're probably ok. So that's quite dodgy then, a copy of a certificate and he has lots of them! Don't pay more than the coins value which is £85 in EF. Vicky Sovereigns are funny things, they start at £50ish, sometimes about £70 for VF, £90 for EF, and then they shoot up to £300+ for UNC! But if it's less than a perfect UNC it's not worth anywhere near the top price. I wouldn't pay more than £60 for it personally, frankly I wouldn't buy anything sold as a novelty item. But my 1871 Sov, which really is UNC, really is very beautiful, has the shield rev and is available to you for the forum member price of £230 (£30 off): http://www.predecimal.com/forsale/gold.htm No novelties, no rubbish, and I'll take it back gladly if you don't like it!
