I must apologise - for my friend zingy66 who has had this for far too long - she has now discovered munzee, and that seems to have taken over for her. I also apologise for not grabbing this earlier - I collected it from zingy on July 16, as I was in my way to a geocaching and munzee event in the New Forest. I had collected several TBs from her, and was in the process of logging them as 'grabbed' - sitting in my card when your coin fell down between of one of the seats. I have searched several times, but today I went further and took apart the parts of the seat that I could. SUCCESS! I retrieved your coin (I cut my hand in the process - several years ago someone decided to smash the passenger side window - there are still pieces of glass under the seat). I will put it in a cache within the week (I hope) - I'll try to find a good cache to put it in, and I hope to get the next souvenir - by visiting a cache on International Geocaching Day.
Sorry once again - but it will be in its travels again soon!
