Last week the Palace manager slapped a £20m price tag on Bolasie, who joined Palace for £400,000 from Bristol City in 2012, but he believes the winger is worth up to three times that.
"I will sell Yannick, if someone wants to give me £40m to £60m, somewhere in there, that would be good," said Pardew, who feels Palace players are undervalued.
"I will take it and we will build the team around that money. Every player has a price, of course. All these players here are undervalued, in my opinion.
"This is a top-10 team at the moment, top 12, yet if you put the valuation of our squad against any of the other teams above us, and some below, it is not right. So I am going to address that. Anyone who rings me up will get a proper price. It is only our second year in the Premier League so it is understandable (if players are undervalued).
"You need to put your credentials there every week. I think these players are starting to do that now; Bolasie, (Jason) Puncheon, (Joel) Ward, (Damien) Delaney. Therefore when I hear figures being talked about players, they are not even close to where I value these players."
