[meteorite-list] Ad: Appraisal Service and T-shirts!

2020-03-28 Thread Bigjohn Shea via Meteorite-list
Dear Fellow Collectors,
Hope you are all doing well today!

After some considerable effort trying to find someone to work on an appraisal 
of my core collection, I have realized that there is a void in the world of 
meteorite collecting. Namely, an affordable and accessible appraisal service 
for meteorite collectors.

When people did have an interest in working on my appraisal, their services 
tended to be unnecessarily expensive, and rarely were they very responsive as 
the effort needed to complete the appraisal is often too time consuming for 
them to perform amidst the other obligations of their life.

For this reason I have decided to offer up my own knowledge and expertise in 
this realm of collecting, and begin performing services as an appraiser. I will 
be using a customized algorithm for determining the valuation of specimens, as 
well as established market values based on prior sales (when needed) to verify 
the valuations of specimens by their merits. This system will make the process 
of forming an appraisal of a collection much easier and as a result be much 
cheaper than a purely hourly rate based method.

The cost of the the appraisal service will be based on the number of specimens 
that are included in the appraisal.

Please contact me at bigjohns...@mail.com for additional details.

T-SHIRTS!
Last but not least, I have added some custom designed "Ultra Cotton" t-shirts 
to my website, which are readily available in L, XL, and XXL sizes. Additional 
sizes can be ordered if needed.

Cheers,
John A. Shea, MD
