Here is my piece of advice Numis, you never stop learning about coins, until the day you decide to stop collecting, The best advice is to ask advice, this is what the forum ia about, its free and we all learn from various members here. I have learnt a lot from these people and i'll never stop asking questions if i'm in doubt about a coin i perhaps have my eye on but unsure about it. As Peckris and Red said, Spink overprice some coins and undervalue others, people who buy the Spink book often rely of what is written, but as someone else said, it's better to look through auctions, not just ebay, but dealers auctions and look at prices paid for coins and their grades. Hopefully you now have a slight insight into the way things work in the coin world and you'll come back with more questions, as i said, never be afraid to ask a question, even if you think it might be a silly question, new collectors are often good soft options for dealers etc and can rush into rash, overpriced, overhyped purchases, i would think 75% of members have done the same in the outset of their starting to collect coins. Viel Spaß, und gute nacht aus München
