Here's some info, in addition to the responses previously posted.
If you know what to look for, a
Full Retail Version, of the
Panther Install CDs, or a
Full Retail Version, of the
Tiger Install DVD, can also be purchased rather inexpensively, at some additional online Apple retailers, Amazon, eBay, FastMac, etc.
As posted, be sure not to purchase grey, upgrade or machine specific CDs or DVDs.
Panther is only on CDs, not DVDs.
Unless purchased from
AppleRescue, the discs should look
exactly like the images in the above links, and not say
Upgrade on them.

As advised in
Gulliver's
Checklist..., Once
Panther 10.3.x is installed, you can use the
10.3.9 Combo Update, to upgrade to the final version.
If your Mac meets the
Tiger System Requirements, you could also consider purchasing and installing that, and then use the
PPC 10.4.9 Combo Update, to upgrade to the current version.
Tiger is available for purchase at
The Apple Store (U.S.).
"Tiger ships on a DVD, but if your Mac doesn’t have a built-in DVD-ROM player, you’ll need CD media."
AppleRescue, also sells a
Tiger installation set on
CD
Shop Carefully, Examine All Documentation, And Good Luck!
