In Need Of Help With 1969-70 Opc Topps

[ryder73]

So being buying some 69-70 montreal Canadiens cards. but they all look the same for this year between opc and topps.
the only difference i can see is that the opc has higher numbered cards in the set but also has the same lower numbered as topps.
how to determine which is which?
i have looked at the backs of all of them and one i have seen on ebay and comc but they all have the tcc marking on the side even the ones people are saying age opc.

if anyone can shine some light on this that would be great, or even a photo to show the difference.

thanks

I believe the ones that are opc are made in Canada and the other ones are USA. I could be wrong but I think that is it.

The backs are also totally different color as well.The Topps are almost a purple while the OPC are blue. And they definitely say printed in Canada.It first say TCC than says Printed In Canada. Plus the carton has a caption in both English and as well as French on the OPC version.
