Reckon they are worth having to a collector who only collects UK releases, there's a lot of these that were never released on a UK 45 in the 1960's so it's the first outing on a UK label.
I always feel that if you are a genuine UK collector, you should be buying these 45s NOW before they disappear and start to fetch bigger cash. The Johnny Sayles on 'Soul City' 'Tell Me (Where I Stand)' is a previously unissued tune...and a corker! Well worth owning IMHO
