Australia - Shipping And Packaging Recommendations

Everyone has their own comfort zone.

Mine happens to be $10 or less.
That means I'll pop a coin worth less than $10 into an envelope and ship without tracking (well protected in a 2x2 and sandwiched between two pieces of envelope-sized thin cardboard).
That comes out to less than 2 ounces.
In the US I can ship that for 99¢.
To Canada I can ship it for $1.50.
For the rest of the world I can ship it for $2.50.

BUT there are many countries I will not ship to at all.
Nowhere in Asia except Japan.
Nowhere in South or Central America.
Nowhere in eastern Europe nor to a large part of the rest of Europe.

It's not the people.
It's that there are too many postal systems that are not trustworthy.

If the item is more expensive ($10 to $20) then most times I'll ship with tracking.
But that means a package, not an envelope.
Problem is that the postal cost jumps considerably.

And above $20 I'll add insurance possibly with signature confirmation.
Now the cost of shipping really gets larger.

It boils down to what chances you are willing to take.

I learned a few tricks from various sellers to be honest.

Buying padded envelops are great but keep in mind that they do add to cost. I personally like to salvage any bubble wrap envelops that I receive and reuse them - they actually do a similar job and you are doing buyers a favor as well.

Bubble wrap is good but not necessary.
If the coin is sandwiched with cardboard then thats enough.
Best way is to do both though.

Water damage is not really an issue.

Thank you all for the comments.

Will the bubble warp adds thickness or weight to the envelop making it more expensive to deliver?

Also when you mentioned sandwich between cardboard, do you have any link or example of where you brought it or use so I can have a better idea without making assumption.

Sorry for the "silly" questions, just trying to keep any future coin buyers happy.

Thanks

I also put coins between cardboard, usually thick(er) one. It makes the package more stable and you can't ''feel'' (or recognize, touch) that there are coins inside.
I have never bought cardboard. I just re-use it from packages send to me (or my neighbour who really likes shopping online) or from cardboard boxes at supermarks. (example: milk is packaged in cardboxes of 10 one liter tetra paks here in Germany; these cardboxes are pretty stable). I just clip the cardboard as I need it.
