Out the gate with no idea what style of art, I'd say $10 is my max on a playing card deck. However, I'm not your intended target audience either. I will say that, if an artist can truly draw me in with their style, I could be made to want to learn playing cards in much greater depth because of the art, and may pay more. I am the type of person that can appreciate an artist's impression, and I actively seek that out in other decks that I buy (tarot, mostly). I want to see things through another person's eyes, and look at cards through a perspective I haven't seen before. I like to be inspired to think differently.
It might be good for you to get specific -- perhaps post some samples of your work and run a poll on price here (if that's allowed).
Here's a link (I hope it's allowed) which show samples from the four decks I mentioned which I have been working on, on and off, over the years:

Of the four, PlanarenKarten ("Planar Cards") is the one which is ready for the printers. All the designs are finished, there's even a box design. My main anxiety with this deck, which is why I have not yet attempted running a crowdfunding campaign for it, is that its art is more... "art history" than commercial art. I sort of have an idea of the look or feel which playing card collectors want, and this style seems to be a bit off tangent from that (as an aside, and this is really generalizing things, the playing card community seems to have more males in it while the tarot-oracle-lenormand-etc community, more females). Anyway, this deck's art may appeal to a number of people but I am not sure if they number enough to lead to a successful crowdfunding campaign.
With Sa Baranggay ("In the Town"), all the line drawings are done. I just need to color the rest. From the images in the sample, you can see I am still eperimenting with a "borderless" or "bordered" look to it for the courts. This is another "niche'y" deck since the style is Filipino-inspired.
The Golden Court is the oldest design of the four. Like 12 years ago. I wasn't much into playing cards back then so there were a lot of playing card conventions and "rules" which were disregarded in the original design and layout. The line drawings are done but it needs a revamp in terms of layout and suit symbols (I'll have to update those sample images because they do not show the suit symbols in the indices).
The last one, Paslit ("Kids"), needs a major revamp. I was just toying around with card size but the tall size really isn't feasible unless I get a lot of backers in crowdfunding - it costs more because I will have to have the printers make me a custom die-cut blade especially for the dimensions of the design. I am thinking of re-drawing the designs to fit a "bridge" or even a "mini" size. Or maybe "domino" size. I am leaning towards bridge because it is the most conventional of the three.
I have checked with POD prices, and TGC surprisingly offers the cheapest and most workable printing costs - but international shipping is a major bummer, and the cardstock isn't really for playing card folks. MPC comes closest to playing card standards in terms of cardstock, but costs twice more - but their international shipping isn't as costly. :-/
