Bertensgrad Pillar of the Community United States 1192 Posts	Posted 12/22/2014 11:35 am I'm starting to sort through a decent pile of Indianapolis transport tokens and I want to divide them into years. I found out a lot of years you can on tell by the metal it was struck on. Is there any way besides the color to tell wheter it's zinc, white metal, or brass. I'm concerned about zinc mostly since from pictures they mostly just look corroded. Does the other metals corrode a lot? Report this Post to the Staff

Buddy Rest in Peace United States 7075 Posts	Posted 12/22/2014 4:51 pm Just a thought ... have you tried weighing them? Report this Post to the Staff
Bertensgrad Pillar of the Community United States 1192 Posts	Posted 12/22/2014 5:38 pm I'm leaning towards that route but there aren't published weights for the tokens so I would have to guess. The one that I can't tel by site is the ones made out of zinc and the brass coins that are plated with a white metal. Report this Post to the Staff
Tryna Pillar of the Community United States 937 Posts	Posted 12/23/2014 10:17 am I have a few odd tokens but do not 'collect' them. Here are a couple of helpful websites if you have not found them already http://www.exonumist.com/ http://www.vecturist.com/ Report this Post to the Staff
Sap Moderator Australia 16849 Posts	Posted 12/23/2014 4:52 pm Zinc coins and tokens turn black in circulation. It also corrodes easily and is prone to zinc rot, the formation of a white powdery corrosion the zinc equivalent of bronze disease or aluminium cancer. The "white metal" plating is probably nickel; try a magnet test. If it sticks strongly, it's made of steel, if it sticks weakly it's probably nickel-plated. Don't say "infinitely" when you mean "very"; otherwise, you'll have no word left when you want to talk about something really infinite. - C. S. Lewis Report this Post to the Staff
Bertensgrad Pillar of the Community United States 1192 Posts	Posted 12/23/2014 5:21 pm Yeah that's what I was thinking with the zinc. They all look terrible when I ever find them. Not sure I could tell one uncirculated. Report this Post to the Staff
Libertad Pillar of the Community Canada 3692 Posts	Posted 12/23/2014 7:08 pm At the time of release transportation companies won't tell you what their tokens are made of. Afterwards when they become obsolete they probably wouldn't care or remember what the metal alloy is. Report this Post to the Staff
