Dont forget items will replicate in the same general area for up to an hour, so you may have provided 5-6 more of the same item with the same graphic to other players on your shard.
Even as a unique item, or one that exists in single or very low double digits I wouldn't value it real high as its a plant graphic and its named rubble. Granted all items are labebled rubble, but for plants which are so common anyways the value will undoubedtly be much lower than the value of building/town objects such as a display case, a vendor sign, a fire pit.
I still expect many of the above items to decrease from their initial value due to the respawn, but there will be select graphics which at most should only exist in the 200+ range across all shards.
