your coin has a weak obv strike. there is still some luster on both sides but glare is a problem that may be enhancing that. its a little banged up on both sides. I think the coin was pulled out of circulation early in its life. the scratch on the obv hurts it.
there is a 56D RPM however I'm not into those so I dont know the markers to look for. there are 18 different varieties of the RPM many can only be distinguished by die scratches.
to be grade worthy the coin needs to be MS67. your coin is not even close. probably AU58 or MS62 at best
it doesn't make sense unless a coin is worth $150 or more. most seasoned collectors dont even slab their coins due to the cost. you could expect to spend about $22 plus shipping/insurance per coin each way plus a subscription to a grading service. PCGS charges a minimum of $69 for a subscription. so you can see it really is not worth grading any average coin.
