Another big gist, wow this is money talking ... Exclusive TMZ Sports has learned Floyd Mayweather used an 18 karat gold pen worth $4,000 thats about N796,200 (In Nigeria Naira) to sign his contract for the big Pacquiao fight. 

They say the Pen is called the Peerless 125 (because there are only 125 in the world) by Cross and it's one of the most expensive writing implements in the world. 

A spokesperson for Cross says he's pumped to add Floyd to the list of "noble" clients who use the company's pens ... including Oprah and President Obama, who has actually signed official docs with a Cross. 

Also Floyd retired the pen after he signed contract ... saying it's now "a part of history."
