Metal detecting Netherlands: Urban Playground raid 7-4-2019

Last Sunday I "raided"some local playgrounds with sandy ground. Most playgrounds have rubber matting, so you have to cherry-pick the right ones. My GoPro messed up a bit, and Im missing some footage from 2 playrounds. I intended to do 7, but ended up doing 4, because some were unreachable due to roadblocks etc. Well the footage of the best 2 are seen here, enjoy! p.s. the unknown coin is a 50 Groschen, Austria 1946-1955 :-P
