If none such appears from said records, similar notice shall be posted at the facility where the death occurred or property shall have been found (if in existence) and at the place where such property is situated at the time of such notice, and also at the place where probate notices are posted in the county wherein the sale is to be had. The person posting such notice shall make an affidavit setting forth the time and place of such posting and attaching thereto a copy of such notice, and such affidavit shall be prima facie evidence of such posting and admissible in evidence as proof of the same.
