There is no single count for every USPS stamp sheet or pane.
Why counts differ
Issue design, denomination, production format, and packaging determine the number. A seller may also bundle several identical sheets into a 100-stamp product.
How to read a listing
Look for the individual stamp count, number of sheets, stamps per sheet, denomination or category, and format. If any figure is missing, ask before ordering.
Count versus value
After confirming the count, multiply it by the current value of that stamp category. Selling price is a separate figure.
