When it comes to the 1979s l have found double 9, double 79 and double 979 making it seem like a full 4 digit double is very rare.
Is this also the case with the 1978s ? lve found double 8s, double 78s and double 978s. Now in this BUC roll l just got l have found 15 which show distinct doubling of all 4 digits.
Are these 15 BUC double 1978s worh a premium or not ?
Thanks guys
