Thanks for your help, I was wondering about that silver one. I thought it could be the onyx, but that pic really makes it look almost silver. I can confirm they are 74 min. discs, I emailed the seller on eBay, but he didn't have the model number. I don't think the U.S. version ever included an orange disc, so they must be foreign. I'ma go check ebay right now. Thanks!

I saw these minidisc blanks for sale on eBay, they look like they come from the Sony color collection (a non-U.S. version, I'm thinking?), but I have never seen these orange and silver ones. Can anyone identify them and if so, where they might be purchased? Thanks in advance!
