Another great dime box. Seems like your finding a lot of '52 & '56 dimes lately. Btw, Im not familiar enough with Canadian coins but I guess u can tell pretty easily which '68 dimes are clad and which are silver huh? And are the '67 Canadian dimes both 50% and 80% silver? That seems a little odd and confusing, but either is sure better than just clad. Btw, I noticed u mentioned u have some banks u can regularly get cwr's from. Have u ever had much luck with quarters? I guess I can assume the answer is probably no but Im thinking about giving quarters a try for a while. And instead of getting boxes maybe I can get like $300 or so at a time to increase my chances of getting cwr's to hopefully increase my chances of finding some silver. I may just confirm quarters r just a waste of time for me but I think I might give them a try for a while.
Lots of 1952D dimes lately, these things come in waves
Despite being 50% Cu, the 1968 Ag Canadian dime looks like any silver dime.
I can tell it is silver by the rim, before I pull it out of the roll.
The 99.9% nickel dimes (1968-2000) have a grayer look.
I have found around a dozen or so silver 1968 dimes in the last 3 years.
The one I found last week was the first one that I couldn't tell by just looking.
It was blackened, so I checked with a magnet.
There is no simple and objective way to tell the difference between a 1967 50% or 80% silver dime/quarter
The design, weight, and diameter are all the same. Some people claim to be able to tell by dropping them on the table and listening but I can't.
The electrical resistance should be different but I don't have a Ohm meter nor do I know if a commercially available one, would be sensitive enough.
Pawn shop have x-ray devices to measure purity of silver and gold, but I don't know If they would do it, out of the kindness of their hearts.
I check small (<$500) amounts of quarters from time to time. I am looking to stay current with my America the Beautiful collection. I haven't found any silvers but I have gotten sometimes shorted (nickels, pennies, plastic stuff, etc.)
It you are interested, I would suggest checking at least $10,000 worth before drawing any conclusions.
There is a lot of coin out there, and it is foolish to draw broad conclusions on small samplings.
