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.

Collector's potential for a 20 peso bill or a 20 peso coin?
About 20 pesos....each.

I think those 20 peso coins are heavier than the Canadian loonie or toonie. They'll have to reinforce pant pockets.
