I understand that you're interested in the value of a 1988 $1000 peso. However, it's important to note that the value of a currency can vary greatly depending on several factors, such as inflation, economic stability, and demand.
With that in mind, it's difficult to give you an exact answer without knowing the specific currency and its current exchange rate. For instance, if the 1988 $1000 peso is from a country with a history of high inflation, it may not be worth much today.
On the other hand, if the currency is from a stable and economically strong country, it may retain a significant portion of its original value.
To get a more accurate answer, I recommend researching the current exchange rate for the specific 1988 $1000 peso you're interested in. You can also consult a financial expert or use an online currency converter to help you determine its current worth.
