Sap is right - that is a souvenir medal. Ramelsloh has been part of the municipality of Seevetal for about 30 years, so I guess your medal is older. But of course there were later occasions to issue such medals too. The church depicted went through a major reconstruction around 1888, so the piece may be from 1988. Just a guess though. The three-digit figure (985?) on the "church side" of the medal indicates the silver content.
