In the last post I did not address the actual cost, but in order to avoid the spread of false information I am posting on the current official costs of death certificates in PA.
There are two very different prices depending on whether you know the exact year of death.
"There is a $9 fee for each certified copy. This fee may be waived for individuals who served or are currently serving in the Armed Forces or their dependents." PA Dept. of Health
"If the year of death is unknown, an applicant may request a multi-year death search. The fee is $34.00 for a search of two to ten years (this fee includes one certification). Additional years may be searched at a rate of $25.00 for a span of two to ten years." PA Dept. of Health
