I'm sure these are CRH PLC Ordinary Shares of 32c each.
When you look at the accounts of CRH on page 12 of the annual report you will see that the share capital is €247m, made up of all of the 0.32's. Below that you will see all sorts of items which when added with the €247 add up to €10.6bn of equity. In simple terms, the vast majority of this latter figure is owned by the shareholders.
I suspect that you probably hold the shares in nominee form, rather than in certificate or crest form, and that you do not get the reports
