Silver plugged 1794/95 Dollars

[1235CE]

Hello all, Been rabidly detecting anbd collecting coins for 25 years but here is a question I could never figure out.....

In 1794-1795 you can find silver dollars that have adjustment marks on them because they used to file off excess silver from an overweight planchet. On underweight planchets they sometimes put a silver plug in the middle of the planchet to make it the right weight.

Can someone please tell me how a silver plug being added to an already silver planchet is going to increase the weight??

Happy hunting and collecting all!

Hi,
Dollar coins of those years were composed of a silver composition that amounted to .8924 silver. Adding a plug of .999 silver would increase the total ampont of silver a very slight amount. The plug would be made to change the silver content to whatever was required by law.

I hope that helps.
