It's been interesting over here ever since the Bay started to allow airguns again. There have been some very strong prices paid for so-so collectables. Now, there is one of the grand prizes in vintage Crosman collectables Model 677 "Plink-O-Matic" in the box on the Bay (381652485697 ) It's the BB version of the model 600. Only made for a couple of years. Very rare. Probably 100 or more 600s for every 677 seen. With the great graphics on the box, it just doesn't get much better in fine Crosman Classics.

Hard to put a price on these things, since they are rare enough that there are few recorded sales. The Blue Book of Airgun Values puts a 95% gun at $450 add 25% for the box, so, $675?
