Hi Crusader,
I don't know much about bale / bag seals. Are they one and the same? I ask because here in the States we often find layered lead disks that have writing / symbols on them and they are always referred to as "bale seals". Normally they are the size of an American dime, but this one is almost the size of an American half dollar. There are no holes in it but its clearly two pieces of lead sandwiched together. There doesn't appear to be writing / symbols on the reverse.
The symbol on the front is curious me as it could be 4 connected crosses of a Maltese type with a fifth cross in the middle. I'm wondering if these could be Spanish.
Ill post pictures of the side and reverse when I get them from my friend.
