I just finished up a roll of 90% SLQ's. These are all in circulated condition and they all have readable dates. I was shocked to see all the extra space when I put them by a tube of Washington quarters I have. Circulated silver really goes away over time. I had to count both rolls twice as I thought I may have miscounted one or the other. Here are a few pics.   |

Wow, that's shocking! I never realized how much was actually lost... That's about $9 in silver your missing!

I know what you mean... It sure made me count both rolls twice.

I suggest weighing them.
The material properties of coin silver are such that a considerable amount of flattening can occur by redistribution of the metal, with very little appreciable loss of weight.
I am actually preparing to start a research project on the wear properties of new silver alloys which have appeared in the market.

I've seen that with halves in tubes before. Not seen people weigh them though

Keeping in mind that the rim of a coin is often the thickest point, a reduction in rim thickness isn't the same as overall reduction in coin thickness. It would be interesting to see if a 10% reduction in stack height resulted in a 10% reduction in stack weight. Thanks for sharing.

The more devices there are - things standing off the fields - the thinner overall the coin will be. More even distribution of the available metal. There is virtually no field on the obverse of an SLQ, and a lot of the reverse of a Washington is interior wing detail of little relief. I wonder if that has a bearing.

Pretty sure these silver coins get squashed into themselves from circulation. Not sure a lot of silver was lost.

The rims, which are there to protect the legends, wear down as well, and in this case, enough to affect the maximum average thickness of the coins.
The SLQ's could also sustain up to about a 15% weight loss.
It would be interesting enough to weigh both lots, and actually calculate the %age weight loss, relative to the same number of unworn 90% silver quarters.

Back in the 1980s I remember once I'd been getting £5 face value bags of 10p coins to sort through from banks. I once filled a bag completely with George VI florins (dated 1947-51) and when the cashier at my dump bank checked it, it was underweight and she had to count out the coins by hand to make sure there was the right amount. Those were cupro-nickel rather than silver coins, but it shows that they had lost a lot of weight over 40 years in circulation.

That happened to me recently with a roll of very worn Buffalo nickels I just sold. The roll seemed way small, and was probably a good quarter to half inch shorter than a roll of little worn Jefferson nickels. I had to recount several times to make sure I didn't mess up. |

You should see what a roll of worn Mercury dimes looks like side by side with a roll of silver roo's from the 60's etc. I also recounted these mercs. many dimes just to be sure. Just be happy that when you sell these worn coins you get paid by the coin and not the actual weight. |

I noticed this a long time ago with Mercury dimes. I have well over 3,000 of them and the most worn ones go into those tubes. Usually about 2 or 3 extra per tube due to wear. Now here is something to wonder about. If yours and others that have had Silver coins wear like that, where did that Silver go? Imagine virtually Billions of Silver coins that have lost a % of Silver. Where is that missing Silver? |

Dimes wiil sustain a greater % weight loss due to wear, than half dollars will.
Five dimes have a greater surface area available to be worn down, relative to to that of a single half dollar, of the same total face value.
