Bought from old Church in England in 1998

I bought these items at an Old Church in England many years ago, the were selling a lot of the items in the church. They told me the cups were pretty old. I think the cups are for drinking the wine ? I'm not even sure what they are made of. There are no markings on them from a company. I tried to clean one as you can see in the picture it's shinny. that's when I found out that you never take the patina off !! Oops. The taller ones stand about 6 1/2" tall and the smaller ones are 2 1/2". The 2 candle holders are3 1/4" tall and on the bottom they are marked "sterling by Longs 880", I'm guessing they are sterling silver? They are very light weight. I'm not to sure if I bought them from the church or at another boot sale. I'd love some info on them :) Could you add "Church" to the categories ?
