Drusy Quartz?

Sorry another money grubber question.
Can anyone tell me if these have any monetary value. I bought them at a storage unit auction but know nothing about them. I believe they may be drusy quartz, but my knowledge is based solely on the information and pictures I can compare with on the internet. I have nearly a1 ton in various sizes.
Any input would be appreciated, on value and or info.
Thanks

They all look pretty damaged so have close to zero value for specimen collectors. Maybe they could be sold for garden decoration?

sorry but to me you are already showing the value a penny!

C'mon Gordon, these are at least nice yard rocks. Certainly not collection quality, but someone would likely go $5 for them. My local garden center has uglier stuff for $20 each.

Maybe there is some cutting value. The matrix would need to be slabbed and worked by an experianced lapidary.
Were there any other rocks in the storage unit?

Here is another I found, not sure what it is. Anyone?

That one is interesting.....I want to say off hand its a calcite. But it has a couple of characteristics that could push me off
that guess. If you have a little pool acid around, a little dab on the surface without the white coating would narrow down the
possibilities. If it fizzes, it would tell you that it’s a carbonate and in all likely hood a calcite crystal cluster.
If the white coating comes off easily with water...it could be of some value.
Locality is important also ( where the specimen was found originally).

That last specimen, if it is calcite as has been suggested, is a lot softer than those large pieces of quartz. Treat it carefully and don't let it rub across anything else as it will be damaged and will lose much of the value that it may have. My guess on the identification - gypsum.

I'm not sure of the exact location, but I do know it was found in western WA. Pool acid = Muratic acid?
The grayish coating seems to come off somewhat with a toothbrush and warm water.

The drusy quartz specimens look like chunks from epithermal veins, in which case the realy interesting minerals might be in the rock rather than the sparkly quartz surfaces. Is there evidence of growth layers in the sides of the rocks? If so, look for fine grained black or gray minerals, or pyrite, or if you are very lucky, tiny reflective bits of electrum (gold-silver alloy) or gold. That is the first thing I would look for, because as everyone else has said, they have no specimen value based on the pictures. Perhaps you could upload pictures of the sides of the rocks so we could see the internal textures better and see if there are layers with other mineralogy in them Also, what region was the storage unit auction in? That might yield a clue,

The storage unit actually belonged to my brother & law, but he lost it, so i bought it at auction. The specimens all came from western Washington state, in the grays harbor area. I will upload some pictures later for an opinion. Thanks for the responses.

Beau,

I didn't see anyone mention it, but it looks to me like the "druse" of crystals is possibly calcite. Try some of the pool acid (muriatic acid) on these and see if they "fizz". I'm betting they will.

Looks like you have about a ton of garden rock, if the photos reflect most of what you have. There is some value in that, but not too much, and you have to find a way to market them to gardeners.

Here are some more pictures. I haven't done anything as far as cleaning them, so they are quite dirty still.

Some more

a good lapidarywould make a frog from the last one. use imagination - like for fish tanks/ponds and other uses.My area sees nothing this good naturally so children are a good target market.

Check the material for fluorescence. Some really unimpressive rock is sometimes of some value to fluorescent mineral collectors.
