Appears so Noost, circulating notes topped out at E56960000A, and they did sell higher numbered sheets.
Not only from a sheet, but from the *same* sheet: This sheet run was printed with skips of 25,000 serials between positions, and your two notes are 225,000 apart, so they'd've been nine positions apart on the same sheet. Looks like somebody might've cut this one up and spent it fairly recently, if they're still together.... Nice finds! By the way, I've been trying to compile information on the modern uncut sheet printings. Here's what I've got so far...if you ever find any sheet notes that don't fit into these serial ranges, let me know, because there are still plenty of question marks floating around the data in places.
