1) Old axial inductor ('choke'), possibly 2.5mH. Still useful to people experimenting with radio circuits, particularly old tube equipment and such like. Not too useful when building semiconductor radio circuits. No longer manufactured, so could possibly be worth a $ or two each if you have a lot of them.
2) Allen Bradley carbon composite resistor, 3.3K. No longer manufactured. Some people still want these for building audio circuits, but they are not hugely valuable, as there are still large stocks out there. $1 each, maybe, if you can find the right buyers, and they want the value(s) you have.
3) Glazed porcelain power resistor, wire wound. Looks like 47 ohm,but could be 4.7 ohm. Nearly indestructible power resistor, still very much useful if you need one of these. Infinite shelf life, but the form factor makes them most interesting to people, who are restoring or repairing old equipment.
4) High stability polystyrene capacitor, 3.3nF. Used for making very stable radio and audio circuits, particularly oscillators and filters. 3.3nF makes this more of an audio component than something you'd use at radio frequencies. Infinite shelf life, and people still want these for various Hi-Fi applications, if you have the value(s) needed. Note: *Highly* sensitive to overheating when soldering.
5) Electrolytic capacitor, junk. No sane person would want these, unless they have a really recent date stamp. Electrolytic caps have a limited shelf life, and if they are 30 years old...
The mounting bracket may be worth a few cents, but they are readily available to anybody, who wants some.
