Potential buyers can bid on the glass tube and a medical form listing Reagan's patient identification number, age, sex, and the hospital's chief cardiovascular and thoracic surgeon, the Post reported. Instructions requested the sample's "lead level" be examined.
The seller wrote he contacted officials at the Reagan Library about buying the vial, but they were only interested if it were donated. Similar efforts with federal agencies were met with similar results.
"Pres. Reagan when he was my Commander in Chief when I was in the ARMY from '87-'91," the man wrote, "and that I was a real fan of Reaganomics and felt that Pres. Reagan himself would rather see me sell it rather than donating it."
The auction opened May 9, with a bid of about $2,370.90. As of late Monday, the top offer for "Lot 160 – Ronald Reagan Blood Vial" was $9,910.36.
Bidding ends Thursday.
