The 2016 Globe CD puts it at $500-650. However, things have gone up since then.
A nice one sold in the Feb 12th, 2017 Morphy's auction for $450, the April 23rd, 2016 Morphy's for $450 and the January 10th, 2016 Morphy's for $500 (all before the juice). Auctions are usually high, but since all of these prices are from about 3-4 years ago, they might be about retail price today. (All of those were Gill / Milkglass BTW)
Price always depends on how bad someone wants it, but maybe this is a good starting point for you.
Hope this helps,
