I am just wrapping up a month-long show with 6 other photographers. There is one who really didn't have a handle on pricing, but she sold 6 of 12 on the first night. The ones that sold are all 8x10 in an 11x14 frame and she sold them for less than they must have cost her to do. I mean, $20-30-35 prices sold. She had equally nice pieces that were slightly larger at 11x14 in 16x20 frames that she priced at $45 and up. At the end of the month, none of those have sold.
I've only sold 4 so far, but they tell me that the last couple of days can make a real difference in sales. At this gallery, they have found that there are people who like to buy on the last day of the show (Saturday) so they can take their picture off the wall and take it home! I've got two people who told me that they are going to do this, so we'll see.
My framed photos are priced at $65-125, depending on subject and size. A couple are just fun shots that I priced at $45-50.
Here are some shots of some framed prints, just to give you an idea. THESE ARE LOUSY SHOTS OF FRAMED PRINTS, but they served my purpose in asking some friends for advice. You will notice that I did NOT link to these images for the person who asked about taking a picture or artwork behind glass, because from THAT point of view, I am embarrassed to show these to anyone. However, they do serve to answer your question for examples of framed work. If you want to see them bigger, just click on any of the thumbnail images.

I sold the laughing cat face in a cheap frame for $50.
The silhouetted lighthouse sold for $125.
My frames are mostly boring. I did this for uniformity of the show. You might make out better matching the frame to the print, as Dawg suggested.
At the opening, a few people asked why I did not have note cards for sale, so I rushed an order for a few different images. I put 24 in the gallery at $3 each and 8 have sold. They were actually only on display for 5 or 6 days so far, though. Since a couple of people ( that's all I spoke to about the notes...) told me that they were not going to use them as notes, but planned to frame them, I am thinking that maybe some plain 5x7 prints might be a good idea. You can get them for about a buck each, put them in a 10¢ sleeve, and sell them for $3-to-5 each.
