We unfortunately can't get the price down to $20-30. We've tried, but the material being used and the labor won't allow us to go that low. They are really nice and sturdy frames.
That's understood - there's a chance it might not be practical for collectors. I think they're absolutely lovely, but they're just too costly. Bear in mind this is simply my opinion - there may be collectors out there who think this is the bee's knees.
For modern deck collectors, it's a tough sell because the rarer, costlier decks people tend to keep in the sealed tuck box (opened decks are often perceived as having lower value) and it's not worth spending $90 to frame a $5 deck. For a VINTAGE collector, however, this could be a much more appealing idea - most vintage decks are found without their box, never mind in a sealed box, and this would allow for displaying a valued deck design while keeping it protected at the same time, in which case, spending $90 isn't such a stretch of the imagination. You should post about this in A Cellar of Fine Vintages. The only issue you'd be likely to run into is that the oldest, most valued decks (more in the antique category than vintage) were not always made in standard poker size - but this is a minor issue at best. There's enough older decks that would fit in this frame nicely to make it an appealing product to vintage collectors. I think a popular subcategory of vintage collectors that would find this appealing would be casino deck collectors.
