1979 P Susan B. Anthony Dollar missing core ?
I have this1979 P Susan B. Anthony Dollar. When you look at the edge, It does not show any sign of copper core. But it weighs 8.2 g. Seeking your opinion.You do not have permission to view this gallery.

The weight on its own shows that it is the correct composition of .75% copper with .25% nickel cladding. Just because you cannot see the copper does not mean it isn't there. The cladding just cover the edge better in your example.Bob Piazza

From the images, the coin appears to be on the correct planchet size.
The coin appears to have a decent reeding all the way around the coin.
The 0.1 in weight difference is probably within tolerance, or as CoinHunter suggests, it may be just enough of a plating that adds more weight to the coin.
They may have wanted to plate the coin to make it look more valuable, its difficult to know what the planned potential outcome was to be.
The SBA and the Sacagawea dollars have the exact same weight and diameter, but in this case, the noticeable difference is the color/metal composition of the coins. a transitional piece would make sense if it was a 1999 version of the SBA, but it is not.
There isn't another coin planchet in the same size and weight range - manufactured for US coins during that timeframe. So it may not be an off metal or wrong planchet, from a US coin. Could it be on a non-US planchet? You would need to research to see if any foreign coins that were struck in 1979 were of the same diameter and weight of the SBA. have a look here:
Foreign coins struck at the US Mint:

Remember - the weight and the diameter (and year) have to be EXTREMELY close.
An unofficial website offers some reference material on US coin specifications for a lot of different US coins. It is listed here:
LC-2560 US Type Booklet_LC-2560 US Type Booklet (littletoncoin.com)
The US Mint does carry a webpage that shows specifications for US coins, but I do not see any older US dollars listed on this page.
It may help others if they are looking for US Mint Coin specifications though.

Good Luck !
