The HL Green Book lists a small number of GLOWs with values greater than retail. These tend to be ones with an early label or edition number.
Presumably each GLOW must stand the test of time - only those pieces that HL expects to be long term sellers warrant a GLOW edition. As such, HL wants them to be as attractive as they can make them within the price point. I assume this is the rationale behind their decision to resculpt. As Open Editions, HL doesn't plan ahead of time to limit the number that are produced just as don't plan to resculpt.
With the resculpting of some GLOW models, it will take a bit of sleuthing to determine how many of each original mold were made before they were redone. But eventually we'll learn about how many of each were made. One might suggest that, in a very narrow sense, these originals are limited editions because there is a fixed number made and a high likelihood the original mold will never be re-used.
Its much too early to tell if there will be a consistent market for these 'fixed edition' GLOWs from original molds. A rather narrow niche and I think its real unlikely there'll be much demand for them. Sure - some wackos who want one of everything the company produces will want each variety, but generally the prospect for GLOW appreciation should be low.
But the fact that there are fixed edition size GLOWs (at least in terms of mold variation) opens the possibility for them to be regarded as Collectibles. And this results in an ever so slight blur of the line betwen GLOW and LE. More varietals, more arcana, more chance of confusion for the new collector.
Imo, HL would be smart not to publish or acknowledge the number of original mold GLOWs (unless it was very high - more than 10k) and downplay any differences between molds.
