How do you show that what you sell was lawfully collected?
Updated
On this page7
Stock is lawful when it left the ground with the right to sell attached, and you can prove it when a written record for each piece names that right. There are five routes: private land with the owner's written permission to collect and resell, a fee-dig site whose terms let you keep and sell, your own mining claim, a federal contract or permit for commercial collecting, and purchase from a seller who documents their source. No federal agency prescribes a form for this record, so you build it yourself. This page sets out each route, the paper it produces, a record layout you can copy and how to handle duplicates from an old personal collection.
Why the record matters more than the rock
A specimen carries no mark that says where it came from. A smoky quartz from a private ranch and one from a BLM wash look the same on the table. What separates them is the source, and federal law cares about the source at every step after collecting, not only at the dig. The Forest Service says hobby specimens "cannot be bartered or sold" [1]; BLM requires "a contract or permit" before anyone collects public-land rocks "for sale or barter to commercial dealers" [2]; and federal fossil rules make it an offense to sell a fossil a person "knew or should have known" was taken from federal land unlawfully [3]. A buyer who resells your piece inherits whatever its source was. The record is how both of you show it was clean.
The material that can never become stock, whatever the paperwork, is listed on selling material collected on public land.
The five lawful routes and the paper each one produces
| Route | What makes it lawful | The document to keep | Watch for |
|---|---|---|---|
| Private land | The owner of the minerals allows collecting and resale | A signed letter naming the parcel, the dates, who may collect, what may be taken and that it may be sold | Severed mineral estates (the surface owner may not own the minerals); checkerboard boundaries with BLM sections |
| Fee-dig site | The operator's written terms let you keep what you find, and do not forbid resale | A copy of the terms or ticket for the date, with the site name | Terms that say "personal use"; state park digs whose rules you have not confirmed |
| Your own mining claim | On a valid claim the locator holds "the exclusive right to the minerals being claimed" [4] | Claim serial number, recording and maintenance records, your field notes tying each piece to the claim | A claim is a mining operation with its own duties; the surface is not private property [4] |
| Federal contract or permit | 8365.1-5(c) allows collecting for sale only after a contract or permit [2] | The contract or permit, with its number, dates, area and material | Collecting outside the permit's area, dates or material |
| Purchase | The seller had one of the routes above, or bought from someone who did | Invoice with date, price, seller's name and address; the seller's source statement; every old label | Sellers who will not name a locality; localities that are parks, monuments or known federal ground |
Two of these routes need more than a sentence. Private-land permission is the one most dealers rely on, and the letter needs specific contents; a checklist of what to agree with the owner is on collecting on private land. Fee digs vary from site to site, and one public example, Crater of Diamonds State Park in Arkansas, has a published rule on how much concentrate a paying visitor may take; whether finds there may be sold was not confirmed from the park, as fee-dig sites explains. Read every fee dig's terms for the words "keep" and "sell."
A record for every piece
Keep one record per specimen or per lot, linked to the specimen by its stock number. The fields below are the ones that answer a land manager, a buyer or a marketplace asking where something came from.
| Field | Example of what goes in it |
|---|---|
| Stock number | Your number, written on or with the specimen |
| Species and description | Species, associated minerals, size in centimeters |
| Locality | As precise as you can record it, with coordinates for self-collected material |
| Land status at collection | Private (owner named), fee dig (site named), claim (serial number), permit (number), or purchased |
| Authority document | The letter, terms, claim record or permit, by file name or folder |
| Date collected or acquired | Day, month, year |
| Collector or seller | Your name, or the seller's name and address |
| Purchase price and invoice | For bought stock |
| Old labels | Kept physically with the specimen, unaltered, in the order received |
| Treatments and repairs | Anything done to it, by you or before you (see disclosure) |
How precise a locality needs to be, and how to write one, is on how precise a locality should be. How to keep old labels and record a chain of ownership is on provenance and old labels. How long to keep business records for tax purposes is a separate rule, covered on what you have to write down.
Keep the authority document, not only a note about it
A line in a spreadsheet that says "private land, owner OK" proves nothing years later. Scan the signed letter, the dated ticket, the permit and the invoice, and file the scan under the stock number or the lot. If the owner gave permission by phone, write to them afterward confirming what was agreed and keep their reply.
Duplicates from an old personal collection
Many dealers start by selling pieces they collected for themselves. The question for each one is the same as for new stock: which route was it on when you collected it?
- Self-collected on private land with permission. Saleable if the permission covered resale. If the owner allowed collecting but never discussed selling, go back and ask, and get the answer in writing.
- Self-collected at a fee dig. Saleable if the site's terms allowed it. If you no longer have the terms, the site may still publish them; keep a copy of the current version and note the date of your visit.
- Bought from a dealer or at a show. Saleable, with the purchase record and old labels.
- Self-collected on BLM, Forest Service or other federal land under the hobby allowance. Not saleable. The allowance was "for noncommercial purposes" [2] and Forest Service hobby specimens "cannot be bartered or sold" [1]. Keep these pieces in the personal collection.
- No data. You cannot show a lawful source, so you cannot pass one to a buyer. Selling a no-data piece as anything other than "locality unknown" misleads; how to handle these pieces is on a specimen with no data.
Keep the personal collection and the stock physically separate from the day you start selling, so the line never blurs. Keeping stock in sellable condition covers how to set that up.
Passing the record on
When a piece leaves you, the buyer needs enough of the record to show their own stock is lawful. For retail buyers that is usually the label: species, locality, and "ex" a named collection when there is one. For shops and dealers buying to resell, send the locality and land-status line with the invoice and keep your own copy. What to send with wholesale lots is on selling wholesale and to dealers.
When the paper has to be a permit
If the stock you want is on public land, none of the private routes applies, and the only way in is a contract or permit obtained before you collect. Which agencies issue them, under which regulations, and what the application involves is on permits to collect for sale.
