not sure if you are aware of the costs of sending a coin in. here is something to consider
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
if you are not familiar with grading here are the costs:
PCGS charges a minimum of $69 for a subscription other subscription levels include grading vouchers though so you could reduce these costs. add to the subscription cost, per coin grading cost which is a minimum of $23, shipping & ins both ways (1-4 coins is $27 if the total value is under $1000)
NGC - economy grading tier is $22, plus $10 handling fee, plus $28 for shipping (1-5 coins) and insurance both ways.
ANACS - Economy - No Gold: $18 per item for items valued up to $500. plus $29 for shipping (1-4 coins) and insurance both ways.
CAC - $99 subscription ($50 grading credit), economy grading $15, gold $28, $40 shipping/handling/ins
