Probably not a meteorite, more likely an iron-rich schist. Cut a slice from it with a rocksaw or have it cut at a shop that cuts granite, then sand & polish a cut side, (never use a file, metal from a file will contaminate the specimen), use aluminum oxide sandpaper, start with 60-grit and work yer way up to 1200-grit, use the 600-1200 grit papers DRY even though their concidered wetsand. Then you'll have a specimen worthy of presentation to a formaly educated geologist who would be capable of identifying it from just a visual inspection.
