I basically agree with what was posted above. Still, considering that nearly 280,000 K0s were produced they represent less than 6% of the total. Taken as a separate model (sub-model might be more accurate) 16K units is more in line with the later model bikes, a comparatively small pool.
That said, so far the only silvertags to command a substantial premium have been documented low-number (the earliest) production...like 10xxxx and the handful I'm talking about were all low-mileage originals, complete with the factory-installed black plastic levers, etc. Even then, there's been less than $1K difference (usually a LOT less) from any other top-flight low-miler or restoration. As for future resale value, who knows...could go the way of the "sandcast" CB750s. The one thing that really works against silvertag collectibility, with the ultra-purists, is the long list of mostly undocumented running changes. Unless it's untouched, you basically have to take the seller's word for what the bike had originally. Even if he's 100% honest, that's still not the same as true documentation, kind of a no-win situation...that results in most of them being nothing more than early K0s, with silver VIN tags.
If you're after a bike to actually ride, the silvertag bikes are probably the worst of the worst and the earlier the D.O.M., the more problems are likely to be present.
