Philippines - ABL (1975-1978) Series other mints (not BSP or FM)

Hi everyone, in the details of 1 Sentimo, 5 Sentimo, 10 Sentimo, and 25 Sentimo I noticed there are different mints for 1975 coins. 1 Sentimo and 5 Sentimo have the Llantrisant Mint and US Mint, and for 10 Sentimo and 25 Sentimo it is US Mint and Vereinigte Deutsche Münzwerke, all of which have high mintage, which of course should be common.

Are there any difference noticeable in these coins that can identify what mint it is? I have plenty of this coins but I can't see any difference as of now.

Thanks in advance for those who'll answer.

These are the coins:
