Hello, I can help with the train notes,
I believe that both notes are 1912 DC-21c, with the signature of (T.C.) Boville.
The current Charlton Book values are as follows.
Dominion of Canada (Train $5) B471795 AU $4000
Dominion of Canada (Train $5) B471780 UNC $6300
Here is a link to Grading Standards;
http://www.cdnpapermoney.com/forum/index.php?topic=129.0The best way to sell these notes depends on your needs.
Check some online auction results, search Ebay for like notes, check with local dealers, visit a local paper money show or entertain offers on this forum.
These things will answer your question as to your quickest and/or most profitable way of selling your notes.
Thanks, Chilliwackdave.
