Baltic amber beads?

Just received these beads as a gift from my mother in law. They are not new by any means. I am wondering if they are coral or Baltic amber? I tried the hot pin test - and there was no smell. I tried the static test - I rubbed one of the beads vigorously on a soft fabric and there was no static but also no smell and no sign of stickiness or tackiness. The other test I read about is taking a knife and testing if it chips or slices. If it chips, I think it is amber and if it slices then it's copal. So for this test, instead of using a knife I examined the head holes which had some chips at the edges, like a glass might look if it was chipped, there was a shinier surface where the chip happened - but this is a one millimeter chip I'm talking about - and I'm no expert so who knows.

So curious if these are amber! My hunch says they are amber but again I really have no idea. Any thoughts about these tests?

Many of the beads are half opaque butterscotch/egg yolk and the other half is more translucent. They really are beautiful no matter what they actually are! I'm going to restring them and wear them myself while I figure out if they are copal or amber.
