37D buffs are very common in high MS grades. i'd call this one in the MS63 to 64 range
as for having it graded. please keep this in mind. most folks, especially new collectors, have no idea what the costs are to slab a coin. most seasoned collectors will only have a coin slabbed for one of two reasons
1. its a rare coin and requires authentication and preservation
2. the coins value is over at least $150 in value and you are planning on selling it
other than these, put it in an album or air tight container. this coin would need to grade MS67 or higher to warrant grading
