Both notes are full regular run prefixes & are heavily circulated.
P-37d Australia $1 - in VG condition would be about $2.00 USD (You can check out Coins & Australia which reports $3.90 in Fine)
P-88a Canada $10 - in F condition would be $10 CDN or about $8USD (no premium until VF+ condition). I'm going by my Charlton Canadian Government Paper Money catalogue. I've sold a few EF+ $10 I had for a 10-20% premium above FV to a few collector friends.
