Out of curiosity, I had a look at one dealer's selling prices in the
current (Australian) Stamp News. The prices, all in $A:
Native Animals $2.50
Non-Olympic: $1.50
UPU: $1.20 - $1.80 (according to perf)
'74 Xmas: $0.80
Education: $2.00
Environment: $0.60
Prime Ministers: $2.00
Science: $2.00
Telecom (perf not specified): $0.30
Famous Women: $3.50 - $4.50 (according to perf)
New Guinea: $0.90
'75 Xmas: $1.10

Ah, those were the days
