In my previous article, I looked at what I might start calling Heads and Tails - stamps printed on the new security backing paper with text in either direction - suggesting that we could have all sorts of problems if people simply unpeeled mint stamps and stuck them back on the backing paper the other way up.
I couldn't figure out whether this would actually make any difference or not so have just tried it with a 5p that I had lying around.
This is the wrong way up - and would be described by one dealer as Small-Large.
This is how it should have been. It would be described as Large-Small.
So, yes, this simple switch does make a difference and we need all to be aware and not splash out on supposedly 'rare' variations. Personally, I think it could even be a bit of a waste of money to collect the genuine heads or tails issues as they're so easy to create that I don't see our children's children getting at all excited about finding these in the collections they inherit in years to come.
