I have been very busy this week offline and not had time to price, and I do not control which cards others choose to price. I also find pricing to be tedious and boring of late, personally, especially when it's not a super rare card (which often get me curious because, well, they're usually obscure cards that are hard to find!). The process is as simple as going to eBay, searching for a card, and then changing the search options to only show the completed listings and then either a) looking for a trend in the prices of the listings that actually sold (these are the green prices in the list of completed listings) or b) adding up the price of each listing that sold and dividing it by the total number of listings that sold - but either one is a pretty tedious process. I could take a stab in the dark and be pretty spot on given that those 4 in particular don't see much competitive play use, though: between $1 to $3 apiece. If you don't believe me, you're welcome to give the methodology I posted a try, since that's what I normally use when I myself am not sure on a price. Checking the prices on Weavile show it's at the bottom end of the range I've estimated, so I'd think its safe to say that the other 3, which are of the same rarity and not used in any competitive decks to my knowledge, are within that same range that most non-holo rares fall into.
tl;dr verion: I've been busy with work and family things and not had the mental energy to price cards because of that, and cannot control what cards others choose to price. $1 to $3 is the most likely range your cards' prices fall into, based on what I've previously known similar cards to be valued.
