Credit Score Prediction

I had my FICO credit score checked for a recent purchase. It had a collection on it from 2-weeks prior though. Since it wasn't my fault they are deleting it and will be able to do a rescore in 8-days. Everything else on my report was in good standing and I probably have 8 years of credit. My score with the collection was 675 and I can only guess what it would be without the collection. FICO scores seem to be a bit of a mystery so googling only helped a little. So I ask everyone to predict what my new score will be based on their own personal experience.



I'll give extra information if needed, but don't want to disclose too much if it's not needed. Thanks!
