Walker And Mercury

From what I see most are common dates but difficult to tell for sure. Could not hurt them much by trying to dip them in some Acetone just to see if some of that dirt comes off. Or just some distilled water. The dirt makes them look a lot worse than they really are. Some are really in decent shape. Always be carefull with the 1942 Mercury dimes. There is a 42/41 and a 42D/41 which both are way up there in values. The 42/41 is really easily noticed. The 42D/41 is kind of difficult to tell. Mercury dimes are notorious for rotated reverses and some as much as 180degrees so watch for that also.
All of your halves would sell for about $7 each at a coin show in G-4 grade and yours are far better than that. Possibly a total of about $40 for the halves alone as a selling price. A dealer should offer you about 20% less for just the halves.

Looks like PVC damage on quite a few of them. Try the acetone as it will not harm the coins and you might get more for them. To most dealers, they are worthless with the PVC scum on them other than silver spot less some percent.

You should haggle for $40 - I'd be happy as a seller at that price with those coins.

They may be dirty but they look to be a little better than the average Walker and a lot better than the average Merc I see for sale around my area. I think $35 would be an OK price for them. I could pick up that lot at a local pawn shop for around $30-$35. If you shopped them around you could probably get $40.

It seems to me from the above, that 10 to 12 x face is the going rate for common average circulated 90% silver.

I went for convenience and a quick sale, sold for $35 off my front door step this morning. Buyer woiuldn't budge to $40. But I did not have to drive anywhere to go sell. Not a bad pick - I got the belt for free 7 years ago. The things people throw away...

Looks like it was better to sell now with Silver at 18, as opposed to 7 years ago at 5.

My shop pays 10x face so you got a fair price for those. They would be in the junk silver category for sure.

Oddly enough I never heard you mention you were trying to sell them. Only wanted to know how much they are worth. If your really planning on selling them, start looking up a possible value on ebay, the PCGS web site, miscellaneous other coin web sites with prices. Then make lots of posts here and get to know who does or doesn't want them and sell to a member here. Remember on ebay or other web sites you have no idea of who is who but here, members tend to not want their names slammed due to poor deals.
