I know someone who has the white box thoth, the bigger size than the purple box, and the lettering is definitely green...but they want $75. The cards are in great shape, but that price is hard for me to swallow. I didn't know if it was an appropriate price for one of these decks.
I'm not sure what would be an appropriate price either. I was very lucky getting mine. I bought it very cheaply from a used bookshop a few years ago. It was my first Thoth and all I knew was it didn't look as colourful as the online scans showed LOL it wasn't until I checked it out on here that I realised it was a greenie. They say that beauty is in the eye of the beholder and with a greenie, it's true. Some people just don't like them.
They still come up on eBay. I think it just depends on what you would want to pay. Maybe someone who has bought one from eBay or a private seller will post and be able to advise you better. I don't think the bookseller who sold me mine knew what he was selling, or he wouldn't have let it go so cheaply.
