The big news for me today is the weather. We got some good northeast wind and are still getting it, although it has shifted a little to the east in recent hours.

| Wind History Shows 24 Hours of Greater Than 19mph At Sebastian. |
The Treasure Coast is supposed to have NE and ENE wind for a few days along with the higher surf.
Unfortunately I wasn't able to go out the last couple of days so I don't have any beach photos for you yet, but it would seem some of the beaches will open up again.---
Jacks4News reports that a shipwreck was recently uncovered by erosion at Crescent Beach.
It appears to be 1800s and not Spanish.

| Pieces of Metal Recently Found On A Treasure Coast Beach. Photo by Kenneth T. |
I received the above photo and following email from Kenneth T.
I had a bit of a natural high digging these things up just south of Jupiter Inlet last week. They were a few feet away from the base of the dunes in a small cut. After digging the 6th one within 30 minutes, my enthusiasm turned skeptical and I thought that they were probably encrusted bottle caps. When I got home and gave 2 of them a muriatic acid bath, here is what I had. No need to clean the other four. All are magnetic. I vaguely remembered you mentioning fake cobs a while back, and after using the search feature on your blog, I pulled up your old post about fake cobs at Jupiter Inlet. I’m not sure if these are fake cobs or just old slugs. They were fun for a few minutes anyway. Thanks for your daily column!
Thanks for writing Kenneth. I used to get a lot of questions from people who had found pieces of iron and wondered if they might be old coins. As you know, a magnet provides a good test, and eliminates a good number of junk finds.
There are some genuine coins that are magnetic though. That includes a lot of German coins, which tend to badly corrode, some Canadian coins, and even a few US coins.
Yesterday I talked about investigating unidentified lumps of metal,. Here is an article that gives you a few ideas on how to identify some common metals. The article isn't great, but you still might find some useful information in it, such as the mohs scale.
That article also provides a link to another page on the mohs scale. The mohs scale is a ten point scale of hardness. The softest materials have low numbers and the hardest (diamond) has a mohs number of 10.
Here is how the scale goes.
1 (softest): tacum, chalk
1.5: tin, lead, graphite
2: gypsum, plaster of paris
2.5-3: human fingernail, magnesium, gold, silver, aluminium, zinc, Jet (lignite)
3: calcite, US penny, copper, arsenic, antimony, thorium, dentin
4: fluroite, iron, nickel, iron nail
5: apatite, tooth enamel, volcanic glass
5.5-6.5: window glass
6: titanium
7: quartz, steel file, ceramic tile
7.5-9: emerald, hardened steel, tungsten, garnet
8: topaz, cubic zirconiam
9: corundom, ruby
10 (hardest): diamond
1.5: tin, lead, graphite
2: gypsum, plaster of paris
2.5-3: human fingernail, magnesium, gold, silver, aluminium, zinc, Jet (lignite)
3: calcite, US penny, copper, arsenic, antimony, thorium, dentin
4: fluroite, iron, nickel, iron nail
5: apatite, tooth enamel, volcanic glass
5.5-6.5: window glass
6: titanium
7: quartz, steel file, ceramic tile
7.5-9: emerald, hardened steel, tungsten, garnet
8: topaz, cubic zirconiam
9: corundom, ruby
10 (hardest): diamond
Titanium is harder than a US penny, and a penny is harder than tin and lead.
If you use this information, it can help you identify different materials, including metal.

That is all for now.
LATER UPDATE: shipwreck items are being found.
