First batch of coins is denars with readable and correct legends, but the corrosion makes me think that they are silver plated contemporary counterfeits. The two left coins are 1537 (https://en.numista.com/catalogue/pieces10702.html) while the right coin is 1585 (https://en.numista.com/catalogue/pieces22144.html).
The second batch is mostly denars which have a garbled legend that gives them away as contemporary counterfeits. This was common at the time, I presume as a way to plausibly deny intent. Since the legends are not decipherable they can't be pinned to one ruler but it is 1500s-1600s.
Third batch is mostly 1430-1437 quartings (https://en.numista.com/catalogue/pieces48166.html). These coins were very low value and crudely made of low purity silver, so I believe they are authentic despite their coppery look. Low purity silver mixed with copper often has a copper look over time. Due to the low value contemporary counterfeits of this type were not often made. There is also a denar of V. Laszlo (https://en.numista.com/catalogue/pieces50712.html) at the right which seems real although I could be mistaken.
Finally the fourth batch is coins I could not identify, so I do not know if they are authentic or contemporary counterfeits.
This is 30 coins in total, I am asking $50 + $3.50 shipping = $53.50 shipped for the whole lot if you are in the US. International shipping would be $14 or $30 by registered mail. This is a great deal to own 400+ year old coins even if many are counterfeits made during the period.
Payment: Paypal F&F or G&S if you have feedback or Cash App. I can do check or money order but I would have to cash it in before sending the coins which may take a couple weeks.
I can also do a swap if you are in the US, especially for junk silver but I can consider anything.
