Jackson, here is the cost of grading at the 4
TPG's
there are really the only two reasons to slab a coin
1. its a rare coin that needs authenticated and preserved
2. you are planning on selling the coin and the cost of acquisition plus the grading fee's would warrant it without chewing up all your profit. I would not grade anything less than $200 and you can see why below
PCGS - Economy grading $23 valued up to $300.shipping & ins both ways (1-4 coins is $27 if the total value is under $1000). PCGS charges a minimum of $69 for a subscription other subscription levels include grading vouchers though so you could reduce these costs.
