The serial number on an AUD 50 note that begins with "GB" indicates that it was issued as part of the Australian currency series. Generally, the serial number can provide information about the year of issue and the batch of notes printed. However, the specific value of the note is determined by factors such as its condition, rarity, and demand among collectors. For an accurate appraisal, it's best to consult with a currency expert or numismatist.
All the answers I saw from googling, said toasters worked by timing. I'm sure that's how they worked when I was a kid, but I don't believe it of today's toasters - if that were so, then why does brown bread take so much longer to toast than white? I presume that, like microwaves, they have some kind of steam detector and that such things must have become, over the years, incredibly cheap. I read on one web page that in the USA you can buy a toaster for $US20 or less. Lucky soandsos: it would be hard to find one in Australia for less than $AUD50, and I'd expect $100.
