Schermack Strip Of 7

I have a strip of 7 #314, type 3. Stamps in position 2 and 6 are hinged, the other 5 are never hinged. Really nice centering, I rate them as VF++ (cannot quite justify superb). Anybody have a clue what this is worth?? We all know that Schermacks are way undervalued, as evidenced by the sales prices on ebay (nice pairs go for up to 4 or 5 times Scott, and strips of 4 go for 8 to 12 times). But - a strip of 7?? I can't even find any evidence of a sale in the last three years. Any help is greatly appreciated. This item is going to PSE for a cert, but they will not grade a strip of 7.

For the private vending coils, I would send it to the PF. Their expert in this field is probably the best. But, I'd agree about a strip of seven. I haven't seen this and very curious about the results of expertization.

(You do know that Scott US Specialized has a separate section for private vending coils?)
