How Do I Send Rolls Of Coins - Proper Packaging.

I would use a small flat rate box. Add insurance as needed.

How about using a Jiffy bag/padded mailing envelope ?

Small flat rate box, but clear tape the ENTIRE outside. I have always done this, even shipping rolls overseas with no problem or loss. A (former) member here shipped me some rolls in a small flat rate box without taping it - he said the Post Office said you couldn't. I got an empty box. They have never told me I couldn't tape.

Yes, those are the boxes. You can pick them up (unassembled) at any post office for free. The $7.65 is the flat rate shipping cost, and insurance and signature are extra. Definitely the best way to go for multiple rolls.

The flat rate box does include postage and comes with an automatic $50 insurance. Not enough to cover two rolls of Morgans but possubly enough for smaller shipments and you can buy more ins if needed. As far as packing INSIDE the box, I would put the rolls in a baggie remove the air and then wrap the rolls with clear shipping tape. This keeps them together as a unit and the baggie keeps the tape from damaging the rolls when it is removed. You don't want the rolls to move around inside the box either so put the rolls in the center of the box and pad around the sides of the rolls with rolled up bubble wrap, or if you have it cut up some styrofoam for spacers, or use shipping peanuts if you have them. The whole idea is to keep the rolls from moving and to cushion them if the box is dropped.

I agree wrapping the box with tape is a good idea. No way this box is coming open accidentally.

If your package value is over $1K you might consider using the brown paper tape and shipping Registered. It is slower but the handling is safer and the insurance costs are lower. Under $1K Priority is cheaper, over $1K Registered is cheaper.

One exception never use Registered for shipping out of the country. Once it leaves the country you can lose the safety of the handling, and once it leaves the country the MAXIMUM liability for the post office is $49 no matter how much it is insured for.

Place rolls in a ziplock bag, or two, roll up, and TAPE the ziplock back around both directions.

Tape the ziplock to the INSIDE of the box.

Add enough packing to prevent the rolls from being thrown about in the box - think...KICK A BALL as hard as you can....and prevent that with the packaging.

They do cover "collectible" coins, they don't cover cash (coverage for cash is limited to no more than $15 unless sent by Registered mail.)

From the Domestic Mailing Manual section 609 filing indemnity Claims for Loss or Damage
4.0 Claims
4.1 Payable Claim
Insurance for loss or damage to insured, COD, or Registered Mail within the amount covered by the fee paid, or the indemnity limits for Priority Mail, or Priority Mail Express (under 4.2), is payable for the following:

a. Article's actual value when mailed.
g. For stamps and coins of philatelic or numismatic value; the fair market value is determined by a recognized stamp or coin dealer or current coin and stamp collectors' newsletters and trade papers. The date of the fair market value determination must be current and prior to the mailing date

Usually they will accept a paid invoice to establish the market value as well.

Oh I didn't say above, but you do have to BUY insurance for the post office to cover them. (With registered mail the coverage comes automatically based on the declared value, which also sets the fee. But like I said, over $1000 registered is cheaper than priority with insurance. And as the value rises it gets a lot cheaper fast.
