Low pressure strike, not grease strike through.

That is a coin struck by a heavily greased die. The tell tale sign for me is the discoloration at the bottom of the cent. If it were a weak strike the facing of the copper plating would be uniform where metal contacted metal. Very thick viscous grease doesn't allow metal to metal contact.

The pressure of the strike should be set to bring up the design, hopefully fully. In the case of a grease strike through especially if there is significant grease, there is now MORE material between the dies than was planned for. this results in a higher than normal pressure strike. The grease though fills the voids in the die preventing the metal from filling the cavities. But the RIMS will fill very well. On a weak strike the center areas will tend to start to fill first starting with the shallowest details first. The last areas to fill will be the deepest details of the die design AND the rims. That is what you are seeing on the coin in question the central details are present but not the deep areas on the obverse (The reverse is pretty low relief all over.) The only place where the rim is struck up at all is on the obverse 9:00 to 3:00. On the rest of the obv and pretty much all of the reverse there is no rim and in fact the "proto-rim" from the planchet is still visible. If this was a heavy Grease Fill, which it would have to be to be missing that much detail on both sides, the rims should be full.
