Greetings. Since Full Bands is a grading designation, the opinion is up to the TPG (Third Party Grading service) who would potentially grade the coin as to whether a dime qualifies or not.
In all 3 cases from the TPG's below, your example would be disqualified from receiving the FB designation due to the lack of separation in the middle bands.
(1) PCGS

- Key statement from PCGS: "In all cases, there must be no interruption of the separation of the subject crossbands, including marks, gouges, nicks, or other surface imperfections."
(2) NGC

- Key statement from NGC: "To qualify for NGC's Full Bands (FB) designation, the two central bands (seen at the center of the coin) must show full separation (with a recessed area between them). The top and bottom groups of bands must also show separation."
(3) CAC

- Key statement from CAC: "Fully split bands are the product of a well-struck coin. The bands must remain uninterrupted from weakness or having disqualifying contact marks."
