Can you visually tell a 40 % half from a 1964, laid face down on a table, reverse up

I can't unless it is a 1964-d.

I suppose there might be some advanced diagnostic between a 64 and a 69 reverse ?

also can you tell the difference between MS-69 and 70 on an ASE ?

Not normally in either case as the slab hides the diagnostic in most cases.

 

Make raw then. 20 1964 halves and 20 mixed from 1965-69. Obverse down on the kitchen table, Ef- unc coins.

Can you tell them apart with a good success rate ? Maybe if something is a tad different on a reverse of 64, that I'm not aware of, otherwise I can't tell.

 

I was thinking more on the line of the graded eagles as I have heard that most of the time what the graders see the holds them back are where reedings clash and leave marks.
Kennedys I have only seen a few of the 40% raw and it was a long time ago. I don't do the roll search thing.

 

From across the room I can get them right four times out of five.
Up close about 19 times out of 20.
It's higher yet if I can touch them.

The 80% clad can be very deceptive but so can the 90% solids. The edge should almost always give it away. Grey is clad and silver is silver. This should work well over 99% of the time.

There are almost certainly diagnostics but I've never taught myself to recognize them because they are quite minor.

 

They tone slightly differently. I'll test myself tonight and see how I do. I'm a pretty big roll searcher so it should be a nice barometer for how easy they are to distinguish.

 

That would be interesting !

 

I'd like to see you hit 80% from across the room on telling 40% from 90 % silver.

 

No offense intended, but I'd love to see that too.

I handle thousands a day sometimes and haven't found any consistant way to get close to that percentage on mixed 40 and 90% just looking at the reverse.

If they are ALL toned, maybe since they tone differently, but no way on mixed bags with untoned coins, at least for me.

 

With the 1964 composed of an amalgam of 90% silver and 10% copper, the outer layers of the post 64's have ±80% silver and a ±20% copper mix that is just a tad bit darker in color. The master die to my knowledge was not changed, just the composition metal, so there would be no distinct diagnostic of the design alone.

 

I can tell 100% of the time.........







But I cheat. I turn the coin over.

 

TO stick up for Cladking I think I could as well. Maybe not if they were all bright BU, but you really won't see those in mixed rolls, right?

On regular bags I spot 40% versus 90% versus clad right away due to different colors.

 

I went about 70% on a mix of BU and circulated ones.

Took ten nice MS ones of each type, dipped 'em, tried again. Went 30% that time.

I can go by sound every time, and rims around 99% of the time. There is the occasional oddball 40%er that really looks like a 90%er on it's rim... but those are rare.

 

I guess it depends what you are going through. I'm just thinking about bags I go through to buy and wouldn't bet the $5 difference in coins that I could be consistant so I guess I'm stuck flipping each coin. I get all kinds of bright coins in both flavors in mixed bags.

It would be great to be able to do it 100% of the time. I'd save hours and hours a week!

 

Over time it's easy to spot the difference from any angle.

 

Circulated are fairly easy to spot because of differing toning of silver verses clad (lighter and whiter). Uncirculated or near uncirculated are harder. But neither are fail proof.
