for that we only need to change the OnPlayerPickupPickup

pawn Код:

new RandomMoney[5] = { 5_000, 10_000, 15_000, ... };

pawn Код:

public OnPlayerPickUpPickup(playerid, pickupid)
{
    if(pickupid == RandomPickup)
    {
        DestroyPickup(RandomPickup);
        SetTimer("CreateRandomPickup", 20000, false);
        new RandomMoneyAmount = random(sizeof RandomMoney), string[10];
        GivePlayerMoney(playerid, RandomMoney[RandomMoneyAmount]);
        Textdraw3 = TextDrawCreate(112.000000,118.000000,"You found the moneybag");
        Textdraw4 = TextDrawCreate(174.000000,79.000000, "Congratulations!!!");
        format(string, sizeof string, "$%d", RandomMoney[RandomMoneyAmount]);
        Textdraw5 = TextDrawCreate(254.000000,146.000000, string);
    }
    return 1;
}

Destroy / Hiding / Changing the textdraw you need to do by yourself
