What's my oil level?

Sorry for the ignorant question but this is my first 225 /6. My dipstick is just a small diameter round rod with a flat dimple about 1-1/2" up from the tip. Is that the full mark? Is that the original dipstick? When I wipe it off, the first 2" is shiny and from there up it's brown. Kinda hard to tell what my oil level is. Is there another flat style one with better markings on it that's interchangeable? Thanks for all y'alls help!
