Shailo of a Reish with small dot

I posted a shailo on the STaM Forum with a picture of a Mezuzah that one of the Reish's has in it a small dot  (turning it into a possible Hei.) The shailo came to the Beis Horah this morning -- the psak was pasul. The Sofer very nicely agreed to let me keep it.
The picture is below, the last word in Shema, "ובשעריך".
