Is there any value to these petrified wood pieces?

[Thanksun]

The long one is normally petrified wood and I think the rounder one is agatised. They're both within the range of a kilo but are both pretty diferrent in appearance.

Without any treatment or grinding and whatnot, are these actually valuable beyond the appreciation of natural beauty in the eye of the beholder?

Petrified wood is unfortunately at the lower value range when it comes to gemstones / minerals and only has value if it is of unusual colour, and even then only if cabbed and put into jewellery. Best kept as part of your mineral collection.
