[pokemondealz4u]

Hello everyone i was told about this fourum from a fellow collector/seller. I have recently purchased a large collection of 1st edition shadowless cards around 200 when going through them to complete an order of 15 cards i discovered a very pronounced 1st edition stamp on the back of a machop ive heard of this error before however it isnt something i see commonly or see for sale either ive done alot of research nd that when my friend told me to come here in the 24 hours i took to actually make a thread i discovered this is so common that everyone with hand full of these cards more then likely has one or in my case 100+… There is a shared error all these back stamps have excluding energies and trainers i cant find the similarity yet… on all back stamps the the window at the bottom above 1999 Wizards look at the Wi theres a blue dot there is another blue dot in that same frame on top left not so pronounced. Lot of these errors might not have a solid visable back stamp however magnified there is a stamp. i have so many examples its nuts. dose anyone have more information on this? i dont know how to upload pictures yet however if anyone would like examples i can provide solid visible ones as well as weak white and black

They can cost you one or two grades.

I found this very hard to read. If you want to post photos of the back-stamps; it will likely generate more responses. Click on the “insert image” button then link to a url that ends in .jpg or .png. For example, you can host photos on facebook or IMGUR or flickr.
