Thank you everyone for your help

Looking through all my German States Stamps, I seem to have an abundance of Bivaria, Wuttemburg, and others, but only one Baden Stamp and a less valuable one at that! I think that it is a great idea to build a collection of certified lesser quality Baden, before investing in higher quality material, Floortrader -- that's exactly what I shall do

ClassicalStamps, thank you for the warning of forgeries; I don't think that I'll begin with buying Baden #1, as, really, I don't think that the risk of forgeries is worth the investment to begin with, but I may revisit the area by buying Official Reprints and refraining from tackling Baden #1 originals, as I don't intend to specialise in the area; the growing pile of Germany just needs sorting out!
Thanks, GeoffHa, for the tip on thicker paper. I 'll just need some certified originals to compare them to *sigh*
Thanks again everyone. This Baden project just got a lot less daunting!
