Likely altered
Bob... I recall buying a group of mid 60s cards many years ago that were improperly stored & cared for.... garage or shed likely... A number of the cards had chemicals which had spilled on them and this cocktail resulted in strange color blotches on the reverse. In my case there was no premium attached, or suggested. They simply went into the offgrade bin and were sold very cheaply. Without knowing the circumstances surrounding this Mantle (provenance, did it turn up alone or in a group, assigned or misperceived value by seller, etc) I would hesitate at speculating what this could be until I could examine it in person
