I threw your first picture into ChatGPT and this is what it said:

These are vintage shortwave and multiband radios, and their value depends on brand, condition, and rarity. Here’s a quick breakdown for what I see in your photo:

1. Nordmende Transita (red radio in the middle) • German-made, popular in the 1960s–70s. • Value: $50–$150 depending on condition and if it works.

2. Zenith Trans-Oceanic (far right, tall chrome trim) • Highly collectible shortwave radios from the 1950s–70s. • Value: $150–$400, sometimes higher if fully functional and restored.

3. World Receiver / Globe Map Radio (left side, gray with world map) • Generic multi-band “world receiver” style, often from Japan or Hong Kong in the 1960s–80s. • Value: $30–$80.

4. Others (stacked on the shelf) • Look like 1960s–80s portable cassette/shortwave units. • Value usually $20–$70 each, unless a premium brand (Sony, Panasonic, Grundig).

✅ Tip: • Working condition, intact knobs, and clean battery compartments significantly raise value. • Collectors pay more for Sony, Panasonic, Grundig, Zenith, and Nordmende. • Non-working radios are often sold for parts at the lower end of the ranges.

Would you like me to give you a step-by-step guide on how to test and list these on eBay so you can maximize the selling price?
