I strive to ship at my cost.  If you pay more at checkout I can refund the overage you may pay.

Rolls and lots: $4.50 for the first roll and $1.50 for each additional roll; up to $8.50.  I can ship up to 30 rolls (paper wrapped) for $8.50.

Single coins up to 3 coins sold at $20 or less: $1.11 for eBay standard envelope.  I ship all of these at 3oz since it is safer that way.  Beyond $20 value shipping is $3.50.

The best way to handle multiple item purchases is to put them in your cart and then ask for an invoice from seller.  That way I can provide these shipping prices without having to issue a refund.

I am not in this business to make money on shipping but I must charge costs involved.  There is no such thing as free shipping.  It is paid for by someone, usually in the cost of the item.
