1971 Washington - Foreign Planchet?

I did not see the mint mark thank you.
Still not sure if it is, or just a crunch mark.
I thought these were produced at Philly,
but if the other ones were made in Denver then I am not sure.

Certainly looks like a normal
Quarter struck on a Nickel planchet,
but as JoCro57 says, the weight isn't
close to a nickel planchet.

With that weight, I believe it is struck
on a Philippine 25 Sentimos planchet.

Weight of that: 61.73 grains, whi

 

No the Philippines 25 Sentimo was struck in Denver in 1971, same place the OP coin was struck. The Liberia piece that Eric mentioned was struck in San Francisco.

That makes the Philippines coin the hands down favorite. A quick check with an XRF gun should confirm it. The composition was 70% Cu, 18% Zn, and 12% Ni

 

Thank everyone for the look and input! Here is a pic of the mint mark from a USB microscope.

I thought this was a possibility as well. I found a copy online of book published by the U.S. Treasury named "Domestic and foreign coins manufactured by mints of the United States, 1793-1976". Below is a screen cap of page 118.



I revisited the coin shop this morning and asked if he could do another alloy analysis. He said it's not scientifically accurate, but the results were:

72% Cu
16% Zn
12% Ni

 

Bingo !

 

Ok am I looking at the wrong guide for coins that are struck at the U.S mint because the one I am looking at is https://libertycoinservice.com/wp-c...s-checklist-foreign-coins-by-us-mint-type.pdf and from what I read on there the Philippines 25 Sentimos was struck in Philly and San Fran from 67-74 and the Liberia 5 cent coin was struck at all three mints from 1960-75. I don't care who's right just as long as it is what most of us are leaning towards which is struck on foreign planchet but I want to know if I'm am reading the guide wrong or reading the wrong guide.

 

.

 

If it has zinc in it then the possibility of it being the Liberia 5 cent coin is nil. If and when you have this verified please keep us updated.

 

Will do! Assuming it is a Washington struck into a Philippine planchet, can anyone ballpark a shipping insurance value? I'm having trouble finding comparable coins sold at auction.

 

Thanks to the folks who reached out over PM. I'll be sure to post the grading results once it comes back.

 

That's really nice.. Wow

@furryfrog02
@Michael K
it was attributed on a Philippine planchet!

I love it when members actually come back and show us that they have something legit!

 

I love it when I actually give a good guess

 

Pretty awesome find! Nice to see a real error here from time to time too.

 

Cool stuff.

 

Glad I could help. Post # 17 (J/K nice coin and attribution.)

 

What would the range of something like that be valued at????

 

@Gigantor what other 3 coins did you submit?
I see that was 004

 

My dealer submitted it with a few other coins. I'm not a collector, so it just made sense for him to broker it.

 

Understood. Thanks for the response!
