House Speaker Nancy Pelosi’s impeachment pens may be worth a pretty penny.

Maryland-based Alexander Historical Auctions said that the 30 customized, black and gold pens Pelosi used to sign the articles of impeachment against President Trump could fetch up to $50,000 each at auction.

That’s $1.5 million. They cost about $20 each.

“There’s nothing like them,” said Alexander boss Bill Panagopulos. Alexander is an internationally-known online auctioneer of historical artifacts and autographs.

Similar to what presidents do when signing significant legislation, Pelosi used one pen for every stroke of her signature.

He said that the value would increase if Trump were convicted in the Senate.

In her signing ceremony, Pelosi handed the pens to lawmakers who played key roles in the impeachment.

Trump later seemed to mock her ceremony when he handed out pens he used to sign the new free trade deal with Canada and Mexico.
