Let me expand on that thought. I don't mean that you have to spend hundreds of dollars on your coins. Learn the true values for the coins you are looking for, then buy the best grade for the money you are looking for. Lets say that you have $25 in your coin budget. Don't buy five $5 coins. Buy 1 $25 coin. A $25 coin that is high for its grade will always be a better deal than the cheaper coin. I hope that makes sense.
