Slabbing advice

[mbarn]

Hi

I have been collecting for a while and would like to look at slabbing some of my collection. i would also be looking to buy coins with the aim of slabbing them. I haven't done this before any advice or help would be appreciated.

As a start :

Who is recommended to have the coins graded and slabbed?
How much does it cost?

What sort of coins should I target - pre-decimal or decimal? or is this irrelevant?

I have some mint Australian pennies i was looking to start with - i'll dig them out and post them here for comments as a start.

any other comments/tips/hints appreciated


Cheers
