I have this 1915 Belgium coin. It has something going on with the date. It looks like it was re-punched. But I am open to comments. There is also an extra dot on the left side of the the date. The book shows an extra dot on the right side but not the left.
These coins are made of zinc, and thus are highly prone to corrosion. This coin has lumps and bumps all over it that aren't supposed to be there; I would tend to assume on an old zinc coin like this that any odd bump that may happen to resemble "re-punching" is just a corrosion bubble.
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
