Sometimes

I think that unless your investing in your coins to sell in the far away future, they will be ok un-certified. I have alot of proof sets I am getting certified, but those are investments for the future. Even if I lose money now on the grading fee's, I win in the long run. The key coins in the 3 Merc Dime sets I have are certified, and even though I bought them as an investment, I love those sets, and will eventually have 3 certified sets, right down to the common 1945-P. It is only worth slabbing a raw coin, in my opinion, if you want to keep the coin safe for your own enjoyment, or if you are making a long-term investment. Posted here is a pic of a common coin I had slabbed, part of a set, but really not worth grading except for long-term re-sale value. Bought it as an AU-58 raw, and it graded MS-63. AU-58 value about $30.00, MS-63 value is $60.00. So to increase the value by $30.00 (I paid $30.00 for it), I spent about $15.00. Anyway, I am anxious to see everyones input on this.
