How true Rob. Welcome Tac Read up on a series that fascinates you.Look at Ebay,auctions,dealers lists and make a reasoned decision. Visit a coin fair. The internet is a great learning resource but I still like a good book. I've been into coins for 40 years and my mistakes are minimal but I still make them. My main passion is early copper(post 1672) there are chancers on Ebay who list key dates at stupid prices.Some times I slip a similar coin in on a 3 day listing undercutting the listings.I get bites. Keep your money in your wallet until you know your subject. My last tip is buy what you REALLY like the chances are others will like it too.
