Bicentennial Proof Set Quarter Uncoated

I have a 6-coin Bicentennial Proof Set in which the reverse side of the quarter is not coated with its silver outside coating. I have yet to find anybody who has heard of this and seeking information re this proof set (quantity made, estimated auction value, etc.) and/or specific information on how to best sell it. It has been about ten years since I last queried about this set. Can anybody shed any information about this set's value? Thank you.

Several years ago I sold an MS business strike bicentennial quarter with no reverse cladding to error coin dealer Fred Weinberg at the Long Beach show for a few hundred dollars.

I'm not an error collector, and have no idea what the population of that particular coin might be. Your proof could be worth more or less on today's market.

 

Thank you Hontonai. Looks like I should find a large show someplace or reputable dealer for error coins. I've never done this. Is there a list of reputable dealers? What is the safe process for sending a coin to such a dealer for examination? I suppose eBay would also be an option. Comments?

 

I already gave you the link to Fred's website. The other member of the "big two" error expeerts is Mike Byers.

Contact either or both and ask about getting your coin verified/appraised. If you live within a reasonable distance of any of the major shows, check whether one of them will be at the next show.

 

definitely sounds like an error

 

Yes it does. Let us know what the 'end of the story' is. And WELCOME to the forum.:hail:

 

Can you post a photo of it?....

I don't ever remember there being a "six" coin Proof set

I don't ever remember there being a "six" coin Proof set during the Bicentennial do you'all????

 

Yep. Black Plastic, red insert.

 

1975 Quarter Reverse

Jim B posted the front of the proof set, except my bicentennial is the 1975 set. Attached is a picture of my reverse showing the unclad quarter. I appologize for the amateur photograph.

 

Could you show a close up of the quarter? It possibly looks toned and not missing the clad layer but it is hard to tell.

 

I tried to zoom in on the quarter and their isn't enough detail on the image after you saved on the resized picture as a jpeg to see it clearly. Can you get another pciture and save it as a PNG. It certainly is interesting.

1975 Quarter Only

How's this? What exactly do you mean by "toned" vs. unclad?

 

mrbrklyn...does the quarter only pic suffice. Since there's a limitation on file size, what is the best format type to use for coin photos? My original .jpg is 2.71M.

 

It looks to me like an error and not toning. We need an error expert. How about as a PNG file instead of a JPG?

I tend to use PNG files because they have more information. Large photos I use JPGs just so that Arizona Jack doesn't yell at me for loading a 10meg file.

where is the TOTW button?

 

I don't think you can nominate a post in the what's it worth section for the TOTW.

 

Color Comparisons

Here is my attempt to show the color comparisons between penny, dime and quarter in the set.

 

Proof error

Ah... too bad. This thread is going to be a learning resource.
