1888 P Indian Head Cent Small Cents Last 8 Over 7

I believe this to be an 1888 last 8 over 7. I have looked at it on a 20X microscope and there is a ridge at the top of the last 8 left and a small protrusion lower left on the last 8. It may be one of the weaker versions that don't command as high a sell price per the Redbook.
