10/17/13 Report - Shark Teeth, Kennedy Half Dollars, Eisenhower Dollars, & More

Written by the TreasureGuide for the exclusive use of

Shark Teeth Recently Found  on the Treasure Coast
Find and photo by William M.
Here is the TBR FOD (Find Of the Day).

The shark teeth were found by William M. along with some other items I'll show below.

Good eye William.  Thanks.

Once again here is something I say a lot, "Keep your eyes open while you detect."   You can find some interesting things that aren't made of metal.  That is especially true when beach detecting conditions are not great.  When sand and shells wash up, so will other things, such as fossils, sea glass, pottery, and sheets of metal.

The Kennedy half dollar coins found in the canning jar that I showed yesterday ranged in date from 1971 through 1983.  Too bad.  That means there is no silver.

In 1964 the Kennedy halves were introduced and were 90% silver.

1965 through 1970, they were 40% silver.

1971 and later, no silver.

Here is a link to a site about Kennedy halves.

The Eisenhower dollars in the jar were 1971 and 1974(2).  Again, no silver.

There were some silver Eisenhower dollars produced by the San Francisco mint, but the ones found in the cache are not silver.

Here is a link about Eisenhower dollars.

There is a 1972 variety worth $90.

It can be worth checking out our coin finds.  You never know when you might have a key date, error coin or some other type of surprised.

Although the silver Eisenhower dollars were not circulated, it is worth checking to make sure.  The silver ones weigh a couple extra grams.  You an learn about that by using the above link.   I'm sure there are a very few silver ones that have found their way into circulation through either ignorance or accident.

I've been seeing so many wheat pennies lately, I've been wondering why.  Just coincidence probably.

Concerning the shell with metal item trapped in concretion, Easy G. said, I was thinking that you could use Coke to dissolve it.  Let it sit for a week or two.  I did that with a wheat penny I found, was a slow process but it does work.

About the same item concealed in concretion, Fred D. said the following.

When I find fossil shells with considerable concretion (or matrix) I go the old fashioned route: soak it in vinegar for a few days. Repeat as necessary. Vinegar breaks down the calcium carbonate (not the silica). It should not harm the metal. It is a light acid but works wonders most of the time. Sometimes not so much. Give it a shot. 

Variety of Objects Found by William M.

Here are some of William's othe finds.  Notice the variety.  Fossil bones, some turtle fossil turtle shell and other bones, sea glass, and encrusted object, and a nice big piece of copper.

William said he ended up walking about six miles yesterday.

Sometimes it is good to just go looking around.  You can occasionally find a new spot worth detecting more heavily in the future.

I would say that most people never take the time to go out and do prospect any new locations.

You might recall that in my formula for detecting success, that the top two factors are location and time on task.

I got an email from Ken H. about his hunting along the Indian River Drive over the past forty years.  He has made a lot of great finds in the area of Susanna, which I was talking about yesterday. He said he might be able to send some photos that I can share.  I hope so.

I hope you took the time to look at the web site giving the history that I gave the other day.  There were some really nice articles and some maps on it.

The low pressure area in the Atlantic that I mentioned a few days ago is now well north of the Treasure Coast, actually up by North Carolina.

The on the Treasure Coast is still in the 2 - 4 foot range.   It will be decreasing down to 1 foot on the 23rd of October if the surf web site projections are correct.  And then increasing a good bit on the 26th.   We might actually get some action by that time, again, if the surf web site predictions are correct.

The high and low tides are relatively high.  Too bad we don't have some bigger waves out there.  They did look pretty nice for a little surfing a couple of days ago - not huge but nicely formed.

Happy hunting,
