I want your opinion on pricing.

Flat rate boxes would be best

I won't give you a price, just because I have NO idea what kind of time and effort you have put into them. I will say FLat rates would be best. Also I am seriously interested in a box full so DON'T SKIP ME lol. I would be interested in a half a box of each!

I think if you have enough material then the flat rate boxes are a great idea. It makes shipping costs actually fairly reasonable given the weight of rocks. The first time I saw someone filling flat rate boxes for their rough listings I thought it was genius. The first time one came in the mail I lifted it off the porch and audibly groaned. I then imagined the mail carrier doing the same and thinking “geez, what’s is in here, rocks?” And then him looking at the return address label and realizing it actually WAS rocks. The thought just cracked me up. 🤣🤣🤣 That was a medium flat rate but there is even the small ones which are great for lesser quantity and more cost effective overall for the buyer. I actually wish more sellers did the small flat rates for this reason.

As for pricing for the material, I’d do online searches and see if any is available for sale or has already sold. Compare quality to what you have and set your price. On eBay you can see sold items and the price they sold for. Once you type your item in the search description, there is a tiny little “advanced” button at the upper right of the webpage that opens a larger menu. I usually check “sold” and also located only in the US to get my sold comparison info. I also look at listings with the sold option not checked to see what’s currently available. These two searches give a good idea both of demand and pricing. I also will try a variety of search terms as not everyone uses exactly the same names.

If you have enough the flat rate is definitely the way to go, personally I like to add some cardboard so the bottom and edges to reinforce a little if it will be packed. I would separate the honey agate and mostly clear or fractured tumbler stone from the nice mossy cabbing material.
A video would help, there is a huge price range in this stuff.

I think I am going to go to the middle ground and go with $1 per pound. Now I just have to get the videos uploaded and put up an ad in the places in the sites I will offer them on.
