The value of pesos compared to dollars can vary significantly depending on which peso you are referring to, as several countries use a currency called pesos (e.g., Mexican peso, Argentine peso, Chilean peso). Generally, however, in terms of currency exchange rates, one US dollar is typically worth more than one peso of any of these currencies.
For example, as of my last knowledge update in October 2023, 1 US dollar could be exchanged for approximately 18-20 Mexican pesos. However, exchange rates fluctuate frequently due to economic conditions, so it's always best to check the current rates for the most accurate information.
