I am new to this as well HeavyT but the advice have had on this forum has generally been great and a vast majority of the people here have been helpful and friendly. As stated above by Rob get a book on grading, it helps massively. You get to learn the most likely wear points on different coins. Also as mentioned already buy some cheaper more available coins to get a feel for how wear effects them and you will start to see the differences between a VF and an EF coin. I am, no doubt, still making mistakes but as long as they are not costing me the earth I do not mind. If you can go to one of the coin fairs, even if you do not plan to buy, as you get to see a huge amount of coins and if gives you a chance to practice your grading. You never know you may find something within budget that you want to buy. Ultimately I am starting to save for a few more significant purchases at the highest grade I can stretch to (at least EF) but if I get chance I will run those past this forum before I go ahead with the purchase.
