Any of these worth purchasing?

All,

Just got these as samples, the guy has kilos of them. which one is better? Also if Steve has any videos explaining the process of recovering gold from these types of scraps, i would appreciated if you could provide the title of the DVD so I can purchase.



and the back of them


Thanks
Kevin
