I love my townhouse but it is so expensive to live in my area that I wish I sold my beautiful townhouse when it was appraised 2.25 years ago for over half a million dollars and moved a little more south to a house with more land for my dogs to run around in the backyard. I am sure it is worth a lot less now with housing prices going down. My real estate taxes are so high also. You are probably right that replacing door knobs will not increase the value of my home a lot but it will help a little bit since those that got top dollar for their homes when my home was appraised had new door knobs and new carpet or hardwood floors put in and crown molding and their kitchens redone. I think I wil finish my bedroom in glass knobs with chrome bases if I can since that will match what I have in the room but the rest of my home I will have to wait awhile and do a little bit at a time. I think the outside door is real brass and is tarnishing but the inside knobs are that cheap painted brass builder's knobs and they are not looking so great after over 16 years (10 years and 2 months I have lived here). Thank you squirrel for caring. I think my home is more of a modern look all over except my bedroom now is a contemporary cottage eclectic look. :)I was trying for Shabby Chic but I like how my bedroom is turning out. I still wish I went with the white honeycombs rather than the linen color. When I have sheers on the windows (when time), I will be happier. I love my Durham Furniture so much and I love my comforter.

I'm not sure about newfangled glass doorknobs, but I grew up in a NYC prewar apartment with the original glass doorknobs from the 1920s, and the doorknobs survived my siblings and vice versa. After my parents died, some 85 years after the doorknobs were originally installed, I was nostalgic enough about the knobs that I removed a few to keep as souvenirs. Still in fine shape and working well, and if one was ever used as a weapon, I'd fear for the victim rather than the knob.

If oil-rubbed bronze is an option, you might want to consider that also. Similar look to black but maybe slightly "warmer." If it's between black and brushed nickle, I vote black! I think theseknobs look nice and are pretty affordable. https://www.amazon.com/Weslock-03700I1I1SL20-Impresa-Oil-Rubbed-Bronze/dp/B004J3WIFE

I have a 20s storybook/ English cottage style home with mahagony stained doors with brass key hole plates surrounded by orginal paint grade casings. Painted wood work with solid dark doors was very common in Victorian, storybook and Spanish style homes built in the twenties. I found a nice replica door via rings end when doing my addition. I used a key plate and knob sourced through a local salvage supply store. Part of the glass knob appeal is the skeleton keys so if you could find real plates and knobs with skeleton keys via salvage yards that would be ideal. Row of small linen closet doors in hallway. The hallway is painted in a dark color so it reads darker with or without the stained doors. Bathroom addition door from rings end with salvaged knob and plate
