freakin' amazing. A purse ! (or "cache" or whatever one wants to call it). And for the crowning glory, you go back to the site and find a few straggler gold coins separately. Sheesk. This is the hole in one / Holy Grail of all md'ing. Other md'rs will now call you "sir". And you can autograph other's detectors.
Looking back at your post history, I see you are from CA. This confirms our suspicions that they were found out west . (Who needs those pesky LC's, colonial coppers, and busts from back east anyhow ?
)
As for the nuggets in with the coins: Have you watched Ron (Rocklin CA) videos ? ("California Relic Adventures" @ youtube). He had a find, before he started making live video captures, from about 15+ yrs. ago, in the Folsom/Auburn, CA area: So although it's not on a video, I'm sure you can find a post or pix of it: He got a signal at the base of a rock/boulder outcropping. He found about a dozen coins, that had apparently , at one time, been a leather or cloth purse (there was a metal clasp of the purse left, if I recall). They were all gold rush era seateds, and a single gold coin (a $5, if I recall). And, like your story, he noticed what appeared to be gold nuggets. He collected all the dirt, and went through the tailing with a nugget detector. And got a bunch of nuggets to go with the coins. A miner who had his purse of both nuggets and coins.
I'm ~3+ hrs. from the Sierra foothills. So I don't get over that way very often for relic hunting. But whenever I have (Snelling to Mariposa corridor) it's always been TOUGH work. There is indescribable amounts of iron and slag around all the gold rush tent-city and stage stop and cellar holes type spots. And coins are very difficult to pull. Much less gold coins. And MUCH LESS GOLD COIN CACHES. Big hats off to you !
