What is billetes de 20 dolares que valen mas?

There are certain types of $20 bills that may be worth more than their face value to collectors. Some examples include:

1. Star notes - These are bills with a star (*) at the end of the serial number, indicating that it was a replacement for a damaged or misprinted bill. Depending on the rarity, a $20 star note can be worth anywhere from a few dollars above face value to several hundred dollars.

2. Low serial numbers - Bills with a low serial number (e.g. 00000001) are also sought after by collectors. The lower the number, the more valuable the bill. For example, a $20 bill with a serial number of 00000001 sold for $5,581.25 in a recent auction.

3. Error notes - Bills with printing errors or misalignments can also be valuable to collectors. For instance, a $20 bill with an inverted watermark recently sold for over $2,500.

Overall, the value of a $20 bill depends on its rarity, condition, and demand among collectors. It's always a good idea to consult a professional appraiser or collector before selling any currency.
