Could these have been mixing transactions?

I'm working on my visualization/analysis tool and stumbled upon these transactions that my tool currently does no detect as potential mixing transactions because they use multiple different denominations.

All of these are quite old so I'm wondering if the PrivateSend implementation was changed at some point to use only a single denomination per transaction.
