Dilemma because of my lack of knowledge

I recently purchased the coin pictured below, an 1853-O with arrows and rays Seated half dollar. The coin has been artificially toned {very well and attractive...but not original}but it does not appear to have been cleaned under high magnification. It seems that whoever owned it before tried to hide a die crack at 3'oclock on the obverse and a die clash under the right wing on the reverse by artificially toning this beauty...It is in an ANACS holder as MS Details/artificial toning.....my dilemma is that I am considering sending it away to the Numismatic Conservation Services to see if it can be restored to original and then graded and encapsulated in an NGC holder....however if NGC won't slab it after restoration then I may have paid for this service and then not like the coin as much in its refurbished state. It wouldn't be that big of a deal { I have a handful of very nice coins in ANACS holders that have have been altered slightly and are very much worth collecting} except that the potential upside of getting this coin in an MS63-65 grade is significant, but as I stated previously, I really like the coin as it is....this is a tough one...
