7/1/26 Report - Jupiter Island at Risk of Breaking. Elongated Penny Metal Detector Find and Collecting. Clump in Progress.

 Written by the TreasureGuide for the exclusive use of the Treasure Beaches Report.


Jupiter Island.

Coastal erosion and flooding, exacerbated by sea level rise, threatens homes and wildlife on Jupiter Island, one of the most affluent beachfront neighborhoods in the country.

Most of Jupiter Island, south of the St. Lucie Inlet, is considered critically eroded for more than 11 miles, according to an inventory of eroded Florida shorelines by the state Department of Environmental Protection.

The erosion is severe enough to potentially "break through Jupiter Island" at a narrow isthmus at Peck Lake outside of town limits, DEP predicted...

Dug Pressed Penny from Frontier Land Machine.

On the end table beside my bed, along with a miscellaneous variety of other small metal detector finds was this tarnished discolored souvenir pressed penny from the Magic Kingdom.  It has been sitting there for a while, but this morning it caught my attention when I realized I knew where it came from.  I've seen the machine that made it.  In fact, the last time I was in the Country Bear Musical Jamboree lobby, I saw some grandparents with their grandchildren getting some made.  But the one above is an older version made a few decades ago before traveling from the Magic Kingdom to one of our beaches before it was lost.  

Pressed pennies are considered to be a type of exonumia.  By one account, the first was made in 1893 at the Chicago's World's Fair.  Reportedly some can bring thousands of dollars.  Even though they make a nice collectible, most aren't worth much more than you'd pay to have them made.  

With pennies disappearing from pocket change, the machines will probably start accepting other coins or make other changes but will undoubtedly survive.

Characteristics of the most valuable.

  • Historical significance and rarity
  • Condition and preservation quality
  • Unique or limited-edition designs
  • Provenance from famous locations
  • Complete collections or sets
Devaluing factors.

  • Common designs from popular tourist locations
  • Poor condition or damage
  • Modern zinc cents (less desirable than copper)
  • Overproduction of certain designs

Here are a couple links for a little more about pressed penny collectibles.

Shell Conglomerate Containing Unidentified Metal Item.

I'm still working on cleaning this clump to expose the metal.  I soaked it in vinegar for at least twelve hours and made very little additional progress.  That is how micro fossils are sometimes found too.

I searched for microfossils in the past but found it too tedious for my liking.  I do think I might see a small fossil in this clump, but will have to put it under the microscope to get a better look.

This is something I'd use Muriatic acid on now if it had some at home.  As it stands, I might end up just breaking open the clump.  It is very hard.

I just noted over half a million views on the treasurebeachesreport.blogspot.com site last month (June).

Nothing new with the tropical weather or surf predictions.

Looks like more of the same.

Good hunting,
