Hi
Peter,
Welcome to the hobby!
If you are ever in Sydney, then perhaps try to make it to one the monthly
ancient coin meetings (ASAN, 4th Monday of the month).
There is also the ancient coin centre at
Macquarie University, ACANS, which
is well worth a visit.
Australasian Coin and Banknote Magazine (CAB) has the occasional ancient
coin article that is worth reading (and some less so!), along with the regular
array of modern articles and notes. The resources are there for you.
Enjoy!
