As of my last update, the value of a Jukebox presorted first-class USPS stamp is typically the equivalent of the current first-class postage rate for letters, which is subject to change. It's usually used for bulk mailing and offers discounted rates for businesses. For the most accurate and current value, it's best to check the USPS website or contact them directly, as rates can fluctuate over time.
