I just discovered the RPF a few days ago, having been made curious by Adam Savage's references over on Tested. I'm quite new to constructing replicas & have only ever purchased a couple of them - and only just created an account when I saw this thread near the front of the site - so please excuse any faux pas!
Having scrolled quickly through this thread, the posts are notable more for the broken links and dead images than the working ones. Given that it appears Quantum Mechanix (QMX) no longer holds the Firefly/Serenity license, would anyone be interested (and would it be permitted, copyright-wise) if I were to make & post high-res scans of the blue (100) and red (500) bills from the Serenity 'Alliance Currency Money Pack' they released? I purchased the QMX 'fan club exclusive edition' pack which includes information from Geoffrey Mandel, the movie graphic designer, confirming the bills are duplicates of the original artwork supplied by Universal. I can't assist with the Firefly currency, but can at least help with ensuring the Serenity currency isn't lost from general 'circulation'.
If anyone is able to share the Firefly currency images, without Photobucket et al. watermarking, that would be excellent - creating paper props is something of an interest of mine, having successfully created everything from steampunk newspapers to replica coasters and business cards, and I'd love to add some Firefly currency to the Serenity pack!
