20 peso bill: Sayonara?

I have heard from a friend of Eloina that the 20 Peso bill will be replaced with the 20-peso coin as soon as the bills need to be taken out of circulation. The newest 20 peso bill was produced in 2021, so will end up as a collector's item. The Bank of Mexico announced that the 20 peso bill will cease to circulate by 2025 and will be replaced with a coin.

"You can go to any bank and request the coins." True? If so, what is the collectors potential? Mickey Mantle baseball cards are worth up to 5000 dollars these days.
