Is there a way to tell the US or Llantrisant Mint ?

Thanks

Not sure if this will help. Not sure myself and have been to busy to take care of. May be a Franklin mint coin.

Sorry my friend was to fast . That is the Franklin mint coin. I know we have talk afew times about this. Good luck

I have several without mintmark.
In Krause you can read (US) and (Lt).
But where is the difference?








I can not tell where these were minted.
Propably the other coins of the Philippines have the same issue.
I think I can catalog these coins in the range of the much minted coins...

Thanks!
As I unerstand, the matte are from the US, the shiny are from Llantrisant.
(Just a guess from Afrasi)

On the bottom left coin, it seems that there is mint mark in the star ?

Little info :
A coin with matte surfaces is one struck from dies which have been sandblasted or acid-etched, giving the entire coin a "frosted", non-shiny appearance. They have been traditionally less desired by collectors than the "regular" mirrored surface or "cameo" combination of frost and mirror.

You may easy verify your guess.

Let us assume that the coins from circulation are of the same proportion as the mintage.
Then a handful of these beautiful coins can be divided in two groups producing the ratio: 6:1. Being so, your guess becomes stronger.

​Not only the die is important. The blancs can be made of polished or non-polished alu
